Answer 1

22.62 cm. I just took this quiz.

Answer 2

The triangle is right angles triangle,

So we can use sin theta here as,

`sin R = (Perpendicular)/(Hypotenuse)`

We are given from figure,

Perpendicular = 5cm and hypotenuse =13cm

Plugging these in the formula,

`sin R = (5)/(13)`

sin R =0.3846

Now here we take sin inverse to get the value of angle R,

R = 22.6189 degrees.

Answer: Angle R is 22.6189 degrees.
