Question 9 and 10

Thanks so much

Answer 1

9 is 62
FEH is 56 so u need to divide by 2
you get 28
you are given a right triangle
a right triangle is 90 degrees
a full triangle is 180 degrees
90 + 28 = 118
180-118= 62

10 is square root 2 because both triangles are the same in size making the line the same
