Answer:
θ = 
Step-by-step explanation:
Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;
Sin θ = 
Sin θ = 
= 0.5
θ =
0.5
θ = 
Thus, the angle of elevation from the base to the top of the mountain is
.
Answer:
26?
Step-by-step explanation
because they are vertical? (i think the word) they are equal so set them equal to each other then solve for x
Answer:
122
Step-by-step explanation:
x = 180-(180-50-72) = 180-(130 - 72) = 180 - 130 + 72 = 50 + 72 = 122
Answer:
B
Step-by-step explanation:
Given that ;
f(x)= x³
f(x)-4 = x³- 4
See attached graph using the graph tool
57.7r + 23.23 =2.57
Subtract 23.23 from both sides:
57.7r = -20.66
Divide both sides by 57.7
r = -20.66 / 57.7
r = -0.358
round to nearest tenth = 0.4
