Answer:
C. He should have divided by 6 when finding the (MAD)
Step-by-step explanation:
He divided by 4 when there were six values.
x=19º
x+9=28º
7x=133º
x+9+x+7x=180
9x+9=180
9x=180-9
9x=171
x=19
its pithagoreon so
c^2= a^2+ b^2
c^2= 32^2 +24^2
c^2= 1,024+576
c^2= 1600
c== 40
x = 115 - p
generally in algebra you will use the letter "x" to represent a value you do not know, so it wants an algebraic expression for "p subtracted from 115", this can be rewritten as 115 - p. So the unknown value "x" is equal to 115 - p.
