Answer:
first one is 42/7 = 6
11*6 = 66
second one
1/2 inch = 3/2 feet
17/2 inches = 17*3 = 51/2 = 25.5
So all the angles of triangle add up to 180 degrees. So you add up the the two other sides and subtract 180 by the answer.
61 + 58 = 119
180 - 119 = 61
So, you’re answer would be 61 degrees. Hope that helped :)
