C) angle of depression and angle of elevation will be the same.
this is because the horizontal for angle of elevation and angle of depression are parallel
therefore, the two angles are same (alternate angles)
hope it helps.
pls mark brainliest !!!
The correct answer is (c) The angle of depression and angle of elevation will be the same.
What is an angle of depression?When a person is standing on top of a hill and looking down at their friend standing on the ground, the angle formed between the line of sight and a horizontal line is called the angle of depression.
Similarly, when a person on the ground is looking up at their friend who is standing on top of the hill, the angle formed between the line of sight and a horizontal line is called the angle of elevation.
Since the two angles are formed by the same two points and are measured with respect to the same horizontal line, they will be congruent or the same. Therefore, option (c) is correct.

Jean and Sarah are buying tubs of ice cream. 2 scoops of ice cream are twice the price of 1 scoop of ice cream. Jean buys 4 tubs with 2 scoops in them and 2 tubs with 1 scoop each. Sarah buys 2 tubs of 2 scoops and 4 tubs of 1 scoop. Sarah spends 2.50 € less than Jean.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the cost of 1 scoop of ice cream. Since the cost of 2 scoops of ice cream are twice the price of 1 scoop of ice cream, therefore the cost of 2 scoops of ice cream = 2x
Jean buys 4 tubs with 2 scoops in them and 2 tubs with 1 scoop each. Therefore the money spent by Jean is:
Money spent by Jean = 4(2x) + 2(x) = 8x + 2x = 10x
Sarah buys 2 tubs of 2 scoops and 4 tubs of 1 scoop. The money spent by Sarah is:
Money spent by Sarah = 2(2x) + 4(x) = 4x + 4x = 8x
Sarah spends 2.50 € less than Jean. Therefore:
Money spent by Sarah = Money spent by Jean - 2.5
8x = 10x - 2.5
2x = 2.5
x = €1.25
Therefore the cost of 1 scoop of ice cream is €1.25, the cost of 2 scoops of ice cream is €2.50.
Money spent by Jean = 10x = 10(1.25) = €12.5
Money spent by Sarah = 8x = 8(1.25) = €10

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The number of cups of rice = 1 cup
The number of cups of water for making rice = 2 1/4 cups of water
So the equation for
The number of cups of water for 1/3 cups of rice =
Number of cups of water for making rice / 3
The number of cups of water for 1/3 cups of rice = 2 ( 1/4 ) / 3
= 9/4 / 3
= 3 / 4 cups of water
Therefore , the number is 3/4 cups of water
Hence , The required number of cups of water is 3/4 cups of water

Check whether -2 is a zero of the polynomial 3x2 + 4x + 32 .
Answer:
x = - 2 is not a zero
Step-by-step explanation:
If x = - 2 is a zero of the polynomial then f(- 2) = 0
f(x) = 3x² +4x + 32
f(- 2) = 3(- 2)² + 4(- 2) + 32 = 3(4) - 8 + 32 = 12 - 8 + 32 = 36
Since f(- 2) ≠ 0 , then x = - 2 is not a zero of the polynomial

Y=-x-2
2x-3y=-9
Solve for x and y
Answer:
y = - x - 2
2x - 3y = - 9
put value of y
2x - 3(-x - 2)= -9
2x +3x +6 = - 9
5x = - 9 - 6
5x = - 15
x = - 3
now put x in y = - x - 2
y = - (-3)-2
= 3-2
y = 1
The cheerleading squad at Kensington High School had 18 members with the old coach. Now, with the new coach, there are 50% more members on the squad, how many members are on the squad now
Answer:
27 members
Step-by-step explanation:
So we have 18 members and we see a 50% increase in members.
So:
Now the squad is 150% of 18
We can set up a percent proportion
x/150=18/100
To solve, we do:
(150*18)/100 = x
27 = x
There is an easier way to do this with benchmark fractions.
We find 50% of 18 which is 9
And since it's a 50% increase, we add 9 to 18 and get 27

Answer:
a.) $10.50
b.) $45.00
c.) about 66.67%
Step-by-step explanation:
a.) regular price = 15.00
discount = 30% or 0.3
15 x 0.3 = 4.50 ----------> this is the amount that you will have off
15.00 - 4.50 ---------> by subtracting from original price, you have sale price
= $10.50
b.) bought price = 25.00
marked up = 80% or 0.8
25.00 x 0.8 = 20 -------> this will give you 80% of 25
25.00 + 20.00 ------> she sells for 80% higher, so add the numbers
= $45.00
c.) original price = 36.00
bought price = 36.00 - 12.00
= 24
24 / 36 -----> divide bought price by original to find what percentage it is
= .66666 which is rewritten as 66.667%
you can check this by multiplying that percentage by the original price

Line segment A B
Line G H
A secant crosses the circle without passing through the center
The secant line is (c) line segment AB
How to determine the secant lineFrom the question, we understand that line segment AB passes through the circle, without passing through the center (i.e. point A) of the circle
This indicates that line segment AB is a secant
Given that the center of the circle is point D
Hence, the secant line is (c) line segment AB
