Given triangle ABC where m<A=45 and m<b=60, find the m<C

Answer 1

The sum of the interior angles of a triangle is 180 degrees. If we express this algebraically we have:

m < A + m < B + m < C = 180

45 + 60 + m< C = 180

105 + m< C = 180

m< C = 75

Ans m< C = 75 degrees

Answer 2

All triangles angles add up to 180°. If we know that one angle is 45°, one is 60°, we can say that angle c is equal to 180-45-60. This is equal to 75.

Hope this helps!
