Question

Find the value of x. Round to the nearest tenth. helpppp image included

Answer 1

`\\ \tt\hookrightarrow sec37=x/17.3`

`\\ \tt\hookrightarrow x=17.3sec37`

`\\ \tt\hookrightarrow x=17.3(1.26)`

`\\ \tt\hookrightarrow x=21.7`

It's approximate value

Answer 2

x = 21.7 (nearest tenth)

Explanation:

Use trig ratio cos(β) = A/H

where β is the angle, A is the side adjacent to the angle and H is the hypotenuse

⇒ cos(37) = 17.3 / x

⇒ x cos(37) = 17.3

⇒ x = 17.3 ÷ cos(37)

⇒ x = 21.7 (nearest tenth)
