To find the measures of the two angles that make up the straight line, we can set up an equation:
(2x+3) + (x-6) = 180
Simplifying the equation, we get:
3x - 3 = 180
Adding 3 to both sides, we get:
3x = 183
Dividing by 3, we get:
x = 61
Now we can substitute x back into the expressions for the angles:
First angle = 2x+3 = 2(61)+3 = 123+3 = 126 degrees
Second angle = x-6 = 61-6 = 55 degrees
Therefore, the measures of the two angles that make up the straight line are 126 degrees and 55 degrees.
A 180° angle (straight line) is formed by two adjacent angles. One angle has a measure of (2x+3)° and the other has a measure of (x−6)°. What are the measures of the two angles that make up the straight line?(1 point)
