Answer:

z= 3

y = 105

x= 90

Step-by-step explanation:

y-12 = 90+z

y-18+z = 90

y = z + 102

z + 102 - 18 + z = 90

2z = 90 - 84

To measure the height of the kite directly above the ground we will need to know the angle of elevation of the kite on the ground.

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

Given here, the length of the string is 100 feet, and the distance of joe to the projection of the kite is 25 feet. Let the angle of elevation be θ then

cosθ=25/100

cosθ =1/4

θ      = cos⁻¹(1/4)

 θ      = 75.52°

Hence, the other we information required to know is the angle of elevation.

The third side of the triangle is 12 units and the measure of the angle θ is 37°.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The third side of the triangle 'a' is calculated by Pythagoras' theorem. Then we have

c² = a² + b²

20² = a² + 16²

400 = a² + 256

a² = 400 - 256

a² = 144

a = 12

Then the value of the angle θ is calculated as,

sin θ = 12 / 20

sin θ = 3 / 5

sin θ = sin 37°

θ = 37°

The third side of the triangle is 12 units and the measure of the angle θ is 37°.

Answer:

  0.25 < x < 2

Step-by-step explanation:

The quadratic can be factored as ...

  4x^2 -9x +2 < 0

  (4x -1)(x -2) < 0

The factors are zero for x = 1/4 and x = 2. The product of the factors will be negative, satisfying the inequality, for values of x that make one factor positive and the other one negative. Those values of x are between x=1/4 and x=2.

The solution is 1/4 < x < 2.

The graph on the number line has open circles at x=1/4 and x=2, and is shaded between those values.

_____

Additional comment

The circles on the graph are open because those x-values are not part of the solution set.

Answer:

a) x = 3

b) 4x

c ) 9x - x

Step-by-step explanation:

a)2x + 4(x -1) = 2 + 4x

2x + 4x - 4 = 2 + 4x

2x[ + 4x [- 4 = 2 [+ 4x

2x + 4x - 4x = 2+4

2x = 6

(Simply both sides by 2)

X = 3

b)25 - x = 15 - (3x + 10)

25 - x = 15 - 3x + 10

25[ - x = [15[ - 3x [+ 10

25 - 15 - 10 = 3x + x

0 = 4x

4x

c)4x = 2x + 2x + 5 (x - x)

4x = 2x + 2x + 5x - 5x

[+4x =[ 2x[ + 2x[ + 5x[ - 5x

2x+ 2x + 5x -5x - 4x

to make the method easy we can divide the fingure into 2 parts

first part

[tex] \frac{1}{2} \times b \times h \\ \\ \frac{1}{2} \times 8 \times 5[/tex]

(because 3+2=5)

[tex] \frac{1}{2} \times 8 \times 5 = {20}^{2} [/tex]

second part

[tex] \frac{1}{2} \times 5 \times 3 = {7.5}^{2} [/tex]

add the 2 areas

[tex] {20}^{2} + {7.5}^{2} = {27.5}^{2} [/tex]

Answer:

percentage decrease is always calculated like this

((orignal - new ) / original ) 100

So in this case

100-45= 55

55/100 is 11/20

11/20 * 100/1 is well simplified is 55

so 55%

5 * 2.60 = 13

He spent $13 on just the video games. Now, he also rented 1 DVD, priced at $4.30.

13 + 4.30 = 17.30

Brian spent a total of $17.30 on rentals in the past month.

Step-by-step explanation:

area of 1 square=1 yd²

A reflex angle is equal to the sum of 180 degreesand any of the primaryangles (acute, right andobtuse angles). Therefore, Reflex angle = 180° + Acute angle.

First, make sure that it is the reflex angle you’re being asked to measure! Lots of children mistakenly, but very carefully measure the wrong angle. Usually, the angle you’re being asked to measure will have a little circle drawn around the point to show you which side needs measuring

2. Make a small mark on your paper to show where 180° is. If you want to, you could even draw a faint line to show the 180° line.

3.You now need to measure the remainder. Using the outside scale on your protractor, measure the angle from the 180° line you have drawn to the second line you have been given (in this case y to x).

4. Add together 180° to the second measurement and this will be your reflex angle.

5. If you want to check your answer, measure the inside angle and check that the two measurements added together equal 360°.
