Answer:

FIND X AND PLUG IT IN

You basically put x+12+2x+3+90=180 and solve for x. Then when you find x plug it in x+12 to find a and 2x+3 to find c.

Answer:

angle A is 37°

angle C is 53°

Step-by-step explanation:

The angles x+12 and 2x+3 add to 90°,  because there is already a right angle in the triangle and the total angles in a triangle add to 180°

x+12+2x+3=90

3x+15=90

3x=75

x=25

Knowing x=25°, we can substitute it back into angle A and C.

A: 25+12=37°

C: 2(25)+3=50+3=53°
