Question

Q.3 In ΔABC ΔB=60º and ΔC=50º, find ΔA​

Answer 1

Answer:

Using angle sum property of triangle

∠A+∠B+∠C=180

∘

⇒35

∘

+65

∘

+∠C=180

∘

⇒∠C=180

∘

−100

∘

=80

∘

Side opposite to largest angle is the longest side of any triangle.

Here ∠C is the largest angle and side opposite to it is AB

So AB is the longest side.

Answer 2

Step-by-step explanation:

here is your answer

I hope it will help you

therefore by angle sum property of traingle

angle A + Angle B + angle c =180

angle A +60 + 50 =180

angle A +110=180

angle A=180-110

angle A =60°
