We are given the measure of the three angles of a triangle as:
51 degrees, 85 degrees , 4 times p degrees
We are asked to find the value of "p".
So we use the property that the addition of all angles in a triengle givew 180 degrees:
51 + 85 + 4 p = 180
we conbine 51 and 85
136 + 4 p = 180
then we subtract 136 from both sides:
4 p = 180 - 136
4 p = 44
we divide both sides by 4:
p = 44 / 4
p = 11
Therefore, p equals 11 degrees.
