Question

Find the value of x. Round to the nearest tenth the diagram is not drawn to scale.

Answer 1

x=10.2

Explanation:

cosine is adjacent/hypotenuse.

In this equation you need to first multiply 11 to both sides which will cancel the first 11.

then multiply 11 to cos(22) and the rest is below.

equation:

cos(22)=x/11

11*cos(22)=x

10.1990224=x

10.2
