Answer:
x = 67.5
Step-by-step explanation:
Because AB and NP lines are parrallel, we can find out the scale factor by dividing size MA by MN.
This works because you find out what the MA size has to be multiplied to to get to MN, which will also work in reverse to find angle MB from MP.
71.5 - 22 = MA = 49.5
71.5 ÷ 49.5 =
So to get to line MP length, line MB had to be multiplied by to get 97.5
The reverse of this is dividing 97.5 by :
97.5 ÷ = 67.5
So x = 67.5
