Answer:hello
Step-by-step explanation:
Given :
Two vertical buildings 57 meters apart are 158 meters and 237 meters high.
To Find :
The angle of elevation from the top of the shorter building to the top of the taller building.
Solution :
Distance between height of building, h = 237 - 158 = 79 m.
Distance between these building , d = 57 m.
Now,

Therefore, the angle of elevation from the top of the shorter building to the top of the taller building is 54.19°.
Hence, this is the required solution.

Answer:
22.09 ft²
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr² . . . . where r is the radius, half the diameter
The slice, at 45°, is 1/8 of the circle, so the area of the slice is ...
A = (1/8)π(15 ft/2)² = 225π/32 ft² ≈ 22.09 ft²
Answer:
2x + 120 = 180 (being co interior angle)
or, 2x = 180 - 120
or, 2x = 60
or, x = 60/2
or, x = 30
therefore 2x = 2* x = 2* 30= 60
