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°
