Answer:

p=39.4°

Step-by-step explanation:

4a+4+75+p=180 (The sum of angles on a triangle is 180°)4a+p=180-4-75

4a+p=101

p+9a+2=180  (Angles of a straight line sums to 180°)

p + 9a = 178

Elimination can be used to find the value of one variable:

p+9a-(4a+p)=178-101

5a = 77

a=15.4

Now, the value of p can be found by using substitution:

4a+p = 101

4(15.4)+p=101

p = 101-61.6

p = 39.4

I hope this helps :)
