Answer:

x = 17

Step-by-step explanation:

Given

\angle 1 = 4x +3

\angle 2= 19

See attachment

Required

Find x

AB and CD being perpendicular, implies that:

\angle 1 + \angle 2 = 90

So, we have:

4x + 3 + 19 = 90

4x + 22 = 90

Collect like terms

4x =- 22 + 90

4x =68

Solve for x

x = 68/4

x = 17

He is correct and incorrect. 2 and 4 can create factors but they can also be factors of other numbers. So 8 can be a factor of bigger whole numbers and can also have it own smaller factors.
