Answer 1

Answer:

35,55

Step-by-step explanation:

let the smaller angle be x

x+20+x=90

$2x + 20 = 90 \\ 2x = 90 - 20 \\ 2x = 70 \\ x = 35$

35,55

Answer 2

Answer:

${\boxed{\boxed{\red{35° \:and \:55°}}}}$

Step-by-step explanation:

Let the angles be A and B.

A + B = 90° (Given)

A = B + 20 (Given). --1

B + B + 20 = 90°. (from 1)

2B = 70

B = 35°

A = B + 20°

A = 55°
