Answer:
Tan 0 = 21/29
Step-by-step explanation:
Use the identity sin(2θ) = 2sin(θ)cos(θ)
You have sin(θ) = 20/29
Given that θ is acute (meaning it's in the first quadrant), and, the opposite side is 20 and the hypotenuse is 29, you can calculate the adjacent side with the Pythagorean Theorem as 21. That means the cos(θ) = 21/29.
So sin(2θ) = 2(20/29) = (21/29)

Jared predicted that the number of mango trees, x, planted in a farm could yield y = (x + 40)² + 60 mangoes per year. What is the minimum value of trees planted per year?
a. 60
b. 70
c. 80
d. 90
Answer:
60
Step-by-step explanation:
The quadratic function tells me that the graph has a vertice at (-40, 60).
So the minimum number of mango yield per year is 60.
Howevery, i believe that there is a mistake in the question;
The quadratic function should be [tex]y = (x-40)^2 +60[/tex]
Because we cannot have negative number of mango tree.
Find the value of 3x
Step-by-step explanation:
If x = 90
So

3x = 270°
Robinson's tapestries all measure 1.5m x 1m wide. Express the proportion of the tapestries' height to width using whole numbers
and ratio notation.
The proportion of the tapestries' height to width using whole numbers is 3:2
proportions are expressed as the ratio ratio two integers. For instance a/b is the ratio of a to b
Given the following sides it a tapestries
Width = 1m
Height = 1.5m
Taking the ratio of the height to the width is expressed as;
Ratio = 1.5 : 1
Writing as a fraction
Ratio = 1.5/1
Ratio = 1.5
Ratio = 15/10
Ratio = 3:2
Hence the proportion of the tapestries' height to width using whole numbers is 3:2

The area of a triangle is 18 square units and the length of the base is 4 units. What is the height of the triangle?
Answer:
I think it’s 9, not sure tho
Step-by-step explanation:
Answer:
The height of the triangle is 4.5 units.
Step-by-step explanation:
The formula for AREA is: L × W/H
So, if the length of the base is 4 units, we can say that if we divide 18 by 4, we will get the missing number (The height of the triangle).

Then, just solve for z:
[tex]7z=4z-3+1\\7z-4z=-2\\3z=-2\\z=-\frac{2}{3}[/tex]
Now, plug that back into GH:

The measure of an angle is 6 greater than half the measure of it’s supplement. Find the measure of the angle
Answer:
64°
Step-by-step explanation:
Set the measure of the original angle as x.
The measure of its supplement would be 180-x.
Thus,
x = 0.5 * (180-x) + 6
x = 90 - 0.5x + 6
1.5x = 96
x = 64°
The measure of angle is 64 degree.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
The measure of an angle is 6 greater than half the measure of it’s supplement.
let the angle be x
supplement of x= 180- x
and, 6 greater than half the measure of it’s supplement.
x = 6 + 1/2( 180- x)
x= 6 + 90 - x/2
x+ x/2 = 96
3x/2 = 96
x= 32 x 2
x= 64
Hence, the measure of angle is 64 degree.

The first thing you must do is ignore the slope which is the number multiplied by x.
The y intercept occurs when x = 0. So all you look at is the sign that follows x and the number after the sign.
The answer is
y = -5x - 12
y = -0.5x - 5
y = -0.5x + 0.5
y = -4.5x + 3
y = 2.5x + 10
Notice choosing the numbers in front of x make no sense. The order seems to be random (and it is). But the number after the x is arranged from smallest to largest.
Answer: y = -5x - 12
y = -0.5x - 5
y = -0.5x + 0.5
y = -4.5x + 3
y = 2.5x + 10

Angle B. Write and solve an equation to find the measure of Angle A.
Answer:
<A = 35 degrees
Step-by-step explanation:
<A = x
<B = 2x
<C = 2x + 5
X + 2x + 2x + 5 = 180 degrees
5x + 5 = 180
5x = 180 -5
