Answer: m<C = 40
Step-by-step 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
Answer:
40
Step-by-step explanation:
sum of angle in a triangle is 180
180=90+50+c
180=140+c
180-140=c
40=c
c=40°
