Answer: it is 6
Step-by-step explanation: because they are the same length.
Answer:
10
Step-by-step explanation:
Answer:
you know that you have the Opposite side and the Adjacent side. therefore you would use Tangent (T= O/A)
because you are finding the angle you would go Tan^-1(12÷20) =31°
it is 12÷20 because O/A and the 12 is the opposite side therefore It would be O and 20 is the adjacent side therefore equaling 20 so O/A = 12/20
Your answer is 31°
15. 145. 360-90-95-30
16. 90
The other picture number 16 again I already did that one.
Since there is no distance between the pole and the base of the tower, we can assume that the pole is at the base of the tower.
We can create a right triangles between the pole and its shadow and between the tower and its shadow as shown in the figure. Let

be the height of the tower. Since our triangles are similar the ratio between its sides is going to be proportional, so we can establish a proportion to find

:


We can conclude that the tower is 137.27 meters tall.
