Question

If angle b= 60° and angle c=50°, find angle a

Answer 1

Answer:-

Given:-

• ∠B = 60°
• ∠C = 50°

To find:-

• The ∠A

Solution:-

We know that,

∠A + ∠B + ∠C = 180°--------(1)

Here, given

∠B = 60°

∠C = 50°

Add the above values in equation ( 1 )

Then,

∠A + 60° + 50° = 180°

∠A + 110° = 180°

∠A = 180° - 110°

∠A = 70°

Therefore, "∠A = 70°"

Answer 2

${\huge{❥{Ans}{wer}}}$

In ∆ ABC

Given :-

B = 60°

C = 50°

Find :-

A = ?

Solution :-

A + B + C = 180° ( Sum of three angles )

A + 60° + 50° = 180°

A + 110° = 180°

A = 180° - 110°

A = 70°
