Step-by-step explanation:
TWO ANGLES ARE COMPLEMENTARY
THEREFORE THERE SUM WILL BE 90DEGREES
2x+(3x-20)=90
2x+3x-20=90
5x-20=90
5x=90+20
5x=110
x=110/5
x=22
2x=2*22=44degrees
(3x-20)=3*22-20
=66-20
=46degrees

Answer:
one angle= 28° second angle= 42
Step-by-step explanation:
90°=2x + (3x - 20)
=(90 - 20)(2x +3x)
5x=70
x=70*5
x=14
2x = 28°
3x=42°
