Question

If A = 30°, C = 90°, c = 713 then a + b =​

Answer 1

Answer:

b=60

Step-by-step explanation:

A=30 C=90 A+B=?

a+b=c

30+b=90

b=90-30

b=60

Answer 2

Answer:

a + b = 60°

Step-by-step explanation:

Given,

a = 30° & c = 90°

a + b + c = 180°

30° + b + 90° = 180°

120° + b = 180°

b = 180° - 120°

b = 60°

So a + b = 30° + 60° = 90°
