Answer:

x = 21.7 (nearest tenth)

Step-by-step 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)

[tex]\\ \tt\hookrightarrow sec37=x/17.3[/tex]

[tex]\\ \tt\hookrightarrow x=17.3sec37[/tex]

[tex]\\ \tt\hookrightarrow x=17.3(1.26)[/tex]

[tex]\\ \tt\hookrightarrow x=21.7[/tex]

It's approximate value
