Answer:
x = 20
angle 1 = 50
angle 2 = 40
Step-by-step explanation:
complementary angles add up to 90
so, you can make this equation:
2x + 10 + x + 20 = 90
combine like terms
2x + x + 10 + 20 = 90
3x + 30 = 90
subtract 30 from both sides of the equation
3x + 30 - 30= 90 - 30
3x = 90 - 30
3x = 60
divide both sides of the equation by 3
3x/3 = 60/3
x = 60/3
x = 20
now, plug x into the angles:
2x + 10
2 * 20 + 10
40 + 10
the first angle is 50°
x + 20
20 + 20
the second angle is 40
