Question

Please solve the question below 22

Answer 1

The value of x is 6.14

Explanation:

Given triangle is a right angled triangle

So we can use trigonometric ratios to find the value of x.

We have to choose a trigonometric ratio that involves hypotenuse and base as we only know one of these and angle

We will use cosine ratio

`cos\ 47 = (base)/(hypotenuse)\\0.68199 = (x)/(9)\\0.68199*9 = x\\x = 6.13791`

Rounding off to nearest hundredth

x = 6.14

Hence,

The value of x is 6.14
