I don’t understand how to find the height

ANTONII [103]

Answer:

height, x is 235 ft

Step-by-step explanation:

From trigonometric ratios:

$\cos( \theta) = \frac{adjacent}{hypotenuse}$

but:

$\theta = 90 \degree - 36 \degree \\ \theta = 54 \degree$

adjacent is x

hypotenuse is 400 ft

$\ \cos ( 54 \degree) = \frac{x}{400} \\ \\ x = 400 \ \cos (54 \degree) \\ x = 235 \: \: feet$

How do I find the value of sec pi/12?

scoray [572]

Sec x = 1/Cosx

Pi radians = 180 degress

Pi/12 = 180/12 = 15 degrees.

Sec15° = 1/Cos15°

Sec pi/12 = Sec 15° = 1/Cos 15°

Cos 15° = 0.9659 using a calculator.

Sec pi/12 = Sec 15° = 1/Cos 15° = 1/0.9659 = 1.0353

Sec Pi/12 = 1.0353
