Answer:

see below

Step-by-step explanation:

1. opposite of cosine  

Cosine = opposite/hypotenuse

There is a reciprocal of cosine called secant  = hypotenuse / opposite

2.    We want to find the height of the tower, y

tan C = y/ x

tan 60 = y/15

Multiply each side by 15

15 tan 60 =y/15 *15

15 tan 60 =y

25.98076211 = y

The height is 25.98076211 m or approximately 26 m

3.  The angle to the nearest degree

tan ? = opposite/ adjacent

tan ? = 27/38

Taking the inverse

tan^-1 (tan ?) = tan ^-1 (27/38)

? =35.39479584

To the nearest degree = 35

Answer:

secant

≈ 26 m

≈ 35°

Step-by-step explanation:

QUESTION 1

Opposite of cosine ⇒ secant  = hypotenuse / opposite leg

QUESTION 2

Height of the tower

tan 60 = h/ 15

h= 15 tan 60 ≈ 26 m

QUESTION 2

tan x = 27/38

x ≈ 35°
