Question

(y-20) digree and (y+30)digree are measure of complementary angles​

Answer 1

Answer:y=50

Step-by-step explanation:

y-20 + y+30= 90 {because its a complementary angle}

2y+10=90

2y=80

y=40

by substituting we get

y-20 {y=40}

40-20=20

y+30{y=40}

40+30=70

so the 2 complementary angles are

70.20
