Answer:
The angle is
.
Step-by-step explanation:
The building is 35 feet tall, and the rope is 400 feet long.Applying the trigonometric function, we have;
Sin θ = 
The height of the building represents the opposite side, while the length of the rope represents the hypotenuse. Thus;
Sin θ = 
Sin θ = 0.0875
θ =
0.0875
= 
The angle made by the rope with respect to the ground is approximately
.
Triangle CGD and triangle CEF both share the same angle at point C.
This means angle GCE equals to angle ECG
Answer: GCE is congruent to ECG
4x(3x + 8) - 7y(5x - 1) =
12x^2 + 32x - 35xy + 7y
The answer is 1.5 because if you divide 117 by 78 you’ll get exactly that ;)
