Answer:

x=60.9°

Step-by-step explanation:

Given that the height of ball from the ground is 150ft

The base of the pole with the ball is 80 ft from where Trey is standing

Trey's horizontal line of sight is 6 feet above ground, then;

The height of ball from Trey's horizontal line of sight is;

150ft-6ft = 144ft

To find the angle x, assume a triangle with a base of 80 ft , a height of 144 ft and a slant height that represent the line of sight at an angle x

To get angle x , you apply the tangent of an angle formula where;

tan Ф°= length of opposite site of the angle/length of the adjacent side of the angle

tan x°= 144/80

tan x°= 1.8

x°= tan⁻(1.8)

x°=60.9°

Find the measure of z

IRISSAK [1]

Answer:

z=55

Step-by-step explanation:

The two angles form a straight line which is 180 degrees

80 + 2z-10 = 180

Combine line terms

70 +2z = 180

Subtract 70 from each side

70-70 +2z= 180 -70

2z = 110

Divide by 2

2z/2 = 110/2

z = 55

Can someone please explain how to solve it ??

if we look on one side, we already have one measurement. 4 cm. ok, that's the measurement on that side. look to the left now. that other side is also the same length, so we take that number and multiply it be 2 to get

$4 \times 2$

Wait! we're not done yet. look at the top. do you see the 3? well that's the width for the top of the rectangle. the bottom must be the same to right? so we get

$3 \times 2$
