Question

21x + 6
what is the value of x?

Answer 1

x=4

Explanation:

The image shows two parallel lines with arrows pointing in opposite directions and it is Perpendicular to the line of its base.

Therefore, 21x + 6 = 90°.

Let's solve for x,

21x + 6 = 90°

subtract 6 from both sides of the equation

21x + 6 -6= 90 - 6

21x = 84.

Divide both sides of the equation by 21

`(21x)/(21)=(84)/(21)`

x= 4

Therefore, Value of x is 4.
