14 x 4.75 is 66.5 and 14 x 1.25 is 17.5
I agree with you, and since you got the right answer, you would know why.
1700/2890 ≈ 0.5882 = 58.82%
However, usually, you should write about 58.82% as it isn't exactly 58.82

5)
x = 132 - 42
x = 90
Answer
90 degrees, right angle
6)
180 - 126 = 54
The other two are congruent so 54/2 = 27
Answer
27
7)
An exterior angle of a triangle is equal to the sum of the opposite interior angles
So
6x = 38 + 82
6x = 120
x = 20
Answer
20
8)
Sum of interior in a triangle = 180 degrees
So
2x - 3 + 23 + 128 = 180
2x + 148 = 180
2x = 32
x = 16
Answer
16
