Question

If you have a triangle with a=90 , angle b=50 , find angle c
​

Answer 1

40

Explanation:

sum of angle in a triangle is 180

180=90+50+c

180=140+c

180-140=c

40=c

c=40°

Answer 2

Answer: m<C = 40

Explanation:

Triangle angle sum theorem states that the interior angles of a triangle sum to 180. We have two angles 90 and 50. Now we need to find the third. 90+ 50 +<C = 180. 140+ C = 180. C = 40
