If angle 1 and 2 are complementary angles and Angle 2 is 20° more than Angle 1, what are the measures of each angle?

They are complimentary so they add to 90. A1+a2=90
A1+20=a2
A1+(a1+20)=90
2*a1+20=90
2*a1=70
A1=35
A2=a1+20=55
Final answer :
Angle 1 is 35 degrees, angle 2 is 55 degrees
Hope I helped :)

when doing equations, you must do the same thing to both sides so that the equation stays equal. also, you want to get the unknown on one side.

so complimentary angles add to make 90 so
x+y=90
x=first angle
y=second angle
y=20+x
subsitute y=20+x for y in x+y=90
x+(20+x)=90
x+20+x=90
add like terms
2x+20=90
subtract 20 from both sides
2x=70
divide both sides by 2
x=35
first angle=35
y=x+20
y=35+20
y=55

55+35=90
