## Answer :

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 :)

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
