Answer:

m<A = 30

Explanation:

The right square is a 90 degree angle

All angles in a triangle add up to 180 so:

x + 37 + x + 67 + 90 = 180

2x + 194 = 180

2x = 180 - 194

2x = -14

x = -7

<A:

x + 37

-7 + 37

30

Answer:

A=30

Explanation:

Set your equation up as following:

180=90+(x+37)+(x+67)

180=90+37+67+2x

180-90-37-67=2x

-14=2x

-14/2=x

-7=x

Angle A = x+37

A=-7+37

A=30
