Question

in a triangle ABC angle A+B=100 and angle B+C =135. find angle A,B and C?

Answer 1

Hey mate,

we know,

In a triangle,

A + B + C = 180°

We know A+B, plug it in the equation,

C = 80°

put C in 2nd equation,

B = 55°

And A = 45°

hope this helps you out!

Answer 2

A+B=100°
B+C=135°
In triangle ABC,
A+B+C=180°
100°+C=180°
C=80°
Since,C=80°,
So,B+80°=135°
B=55°

Now,B+A=100°
55°+A=100°
A=45°
