Question

A skateboard ramp forms at 42 degrees angle as shown find the x value

Answer 1

x=23

Explanation:

its a straight line which equals 180 degrees. 180-42=138 and then 138 divided by 6 equals 23.

Answer 2

The value of the variable x is 23

To determine the value of the variable, we need to take note of the following;

• Angles on a straight line equals 180 degrees
• Alternating angles are equal
• Corresponding angles both sum up to 90 degrees
• Supplementary angles both sum up to 180 degrees

Then, from the diagram shown, we have that;

6x + 42 = 180

collect the like terms, we get;

6x = 180 - 42

subtract the values

6x = 138

divide the values

x = 23
