Given m∠A=39° and m∠F=56°, what is m∠C?

85 degrees

Step-by-step explanation:

In similar triangles, corresponding angles are congruent, or have the same measure.

Therefore, angle B must also be 56 degrees. In a triangle, there are 180 degrees.

A+b+c=180

39+56+c=180

c=85 degrees.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
