Answer:
The value of angle P is 119 degrees
Explanation:
When two angles are supplementary, it means that they add up to be 180 degrees. For example, if we have two angles only on a straight line, then both angles are supplementary angles.
Now, the information we have from the question is that angle P is three less than twice the measure of Q.
What this mean is that if Q is x, then P is 2x-3
So let’s add both to equal 180 since they are supplementary;
x + 2x -3 = 180
3x -3 = 180
3x = 180 + 3
3x = 183
x = 183/3
x = 61
This is the value of Q;
The value of P which we are asked to look for is 2x -3 = 2(61) -3 = 122 -3 = 119 degrees
