Both angles are complementary angles, or they together equal 180°, so you will add both expressions and set equal to 180. This will get you (3x+2)+(5x+10)= 180. We then solve for x. 8x +12 = 180. We subtract 12 on both sides. 8x = 168. We divide by 8 on both sides. x=21 We can then plug x into each expression to get the angle for each. Angle 1: 3(21)+2=65° Angle 2: 5(21)+10=115°
