The answer would be p = 1.
10p + 5 = 18p - 3
5 = 18p - 3 - 10p
5 = 8p - 3
5 + 3 = 8p
8 = 8p
Divide 8 by 8 ( 1 = p)
switch sides ( p = 1).
Right scalene triangle, because each side is a different length.
The answer is D. 42
A triangle equals 180 in total so what you would do it subtract 122 from 180 because 180 is also the angle of a straight line. You would get 58 then you add 58 and 80 to get 138. Subtract 138 from 180 and you get your answer of 42
