Answer: 32° & 58°
Explanation:
"Two angles are Complementary" means: x + y = 90
"Sum of the 1st angle plus twice the 2nd angle is 148" means: x + 2y = 148
Solve the system using any method (I am using elimination)
x + y = 90 → -1(x + y = 90) → -x - y = -90
x + 2y = 148 → 1(x + 2y = 148) → x + 2y= 148
y = 58
x + y = 90
x + 58 = 90
-58 -58
x = 32
