Three angles have measures that add up to 180 . They have the following angle measures: m< ABC = (x - 6) , m<CBD = (4x - 14) , and m<DBE = 5x . What is the equation to solve for x?
answers:
10x + 20 = 180
10x - 20 = 180
x - 20 = 180
9x - 20 = 180
The correct equation to solve for x is:
x - 6 + 4x - 14 + 5x = 180
Combining like terms:
10x - 20 = 180
Are you sure
I apologize for the confusion. You are correct, the equation should be:
x - 6 + 4x - 14 + 5x = 180
Combining like terms:
10x - 20 = 180
Two supplementary angles have the following measures: m<ABC = 135 and m<CBD = 9x . What is the equation to solve for x?
answers:
9x + 135 = 90
9x + 135 = 180
9x - 135 = 180
9x = 180
The correct equation to solve for x is:
9x + 135 = 180
you sure
Apologies for the mistake. The correct equation to solve for x is:
135 + 9x = 180
Two angles are supplementary and have measures m<QRS = (x + 40) and m<SRT = x. What is the measure of <QRS

The measure of angle QRS can be found by setting the sum of the two angles equal to 180, since supplementary angles add up to 180 degrees.
So, we have:
(x + 40) + x = 180
2x + 40 = 180
Now, solving for x:
2x = 180 - 40
2x = 140
x = 70
Therefore, the measure of angle QRS is:
m<QRS = x + 40 = 70 + 40 = 110
Therefore, the correct answer is 110.
