To find the measure of angle ABC, we need to set the expression for angle ABC equal to a given value.
Given:
m∠ABC = (3x + 8)
m∠ABC = (5x - 40)
Set the two expressions equal to each other:
3x + 8 = 5x - 40
Subtract 3x from both sides:
8 = 2x - 40
Add 40 to both sides:
48 = 2x
Divide by 2:
x = 24
Now substitute x back into one of the expressions:
m∠ABC = 3(24) + 8
m∠ABC = 72 + 8
m∠ABC = 80°
Therefore, the measure of angle ABC is 80°.
Given:
m∠ABC = (3x + 8)
m∠ABC = (5x - 40)
Set the two expressions equal to each other:
3x + 8 = 5x - 40
Subtract 3x from both sides:
8 = 2x - 40
Add 40 to both sides:
48 = 2x
Divide by 2:
x = 24
Now substitute x back into one of the expressions:
m∠ABC = 3(24) + 8
m∠ABC = 72 + 8
m∠ABC = 80°
Therefore, the measure of angle ABC is 80°.
