1) what is the value of x ? 2) what is the measure of angle ABC
3) what is the measure of angle CBD

Measure of angle ABC = (3x)°

Measure of angle CBD = (15x+18)°

Since angle ABC and angle CBD are a linear pair their sum will be equal to 180°¿

Which means :

Thus, the value of x = 9.

From that equation, we know that the value of x = 9.

Which means :

Measure of angle ABC :

Measure of angle ABC = 27°

Therefore, the measure of angle ABC = 27°

We know that x = 9

Which means :

Measure of angle CBD :

Thus, angle CBD = 153°

Since the measure of angle ABC and angle CBD equals 180°[27+153=180°], we can conclude that we have found out the correct value of each angle.

Therefore, the measure of angle CBD = 153°

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
