Question

Could someone help me please

Answer 1

I think A is 60 because 30+90=120+60=180

Answer 2

The first one is m A + 30 + 90 = 180

Second is 60

Explanation:

A triangle’s added up angles ALWAYS equals 180.

The formula here is to subtract the two known angles from 180 and the answer leaves you with the unknown angle.

180 - 90 - 30 = A

So,

180 - 90 - 30 = 60

You can check by adding all the angles and it adding up to 180

90 + 30 + 60 = 180
