Question

5) In a triangle ABC if BC = AC and angle ∠B = 35°, find value of angle ∠C.​

Answer 1

Answer:

$\angleC$ is 110

Step-by-step explanation:

Given that in triangle ABC, BC = AC

Thus, triangle ABC is a isosceles triangle

and $\angleA = \angle B$

And we have$\angleB = 35$

Thus, $\angleA = 35$

Also, we know

Sum of all angles of triangle is 180

Thus, we get

$\angleA + \angleB + \angleC = 180\\\\35 + 35 + \angleC = 180\\\\ 70 + x = 180\\\\ \angleC = 180 - 70\\\\ \angleC = 110$
