Question

In ∆ABC, /_ A = 60° and /_ B = 30°, what is C=​

Answer 1

We know that the sum of all the angles of a ∆ is 180°

So, 60° + 30° + x° = 180°

90° + x° = 180°

x° = 180° - 90° = 90°

x = 90 °

Answer 2

Step-by-step explanation:

<A=60

<B = 30

<A+ <B + <c = 180 (Angle Sum Property)

60+30+ c = 180

90 + C = 180

c = 180-90

C = 90 degree
