Answer:
86°
Step-by-step explanation:
Normally, the building stands at an angle of 90° to the ground (from horizontal)
so,
x = 90° - 4° = 86°
1 second = 11%
2 seconds = 22%
45 × .22 = 9.9
answer: 9.9 meters
<span>If the triangle has an obtuse angle (>90 degrees), it can be classified as an obtuse triangle Not sure where the 42 inches is used Hope this helps</span>
8y^2 + 12x - 4y^2 + 24x
= 4y^2 + 36x
