A triangle has sides of length 3 cm, 5 cm, and 7 cm.
BlackZzzverrR [31]

Answer:

C=120 degrees

Step-by-step explanation:

We can use the law of cosines to find an angle when we have all three sides

(7)^2 = (5)^2 + (3)^2 -(2)(5)(3)Cos(C)

49 = 25 +9 -30Cos(c)

49= 34 -30Cos(c)

15 = -30Cos(c)

Cos(c) = -1/2

C=120 degrees
