Question

It’s about angles use an equation to solve and ABCD?
And what is the measure of RST?

Answer 1

A. 40 degree+ 90 degree = x

The sum of the angles = 130 degree

Explanation:

`Given:\:\:\angle RSV = 40\degree,\:\:\angle VST = 90\degree\\\because \angle RSV + \angle VST = \angle RST\\\therefore 40\degree + 90\degree = x`

x = 130 degree

Answer 2

The answer is C)
