Answer:If the vertex angle is x, then the base angle is 2x. Since the base angles of an isosceles triangle are equal, the other base angle is 2x.
The sum of the angles of a triangle are 180 so: x + 2x + 2x = 180 and x = 36 and 2x = 72.
Thus, the vertex angle is 36 degrees and the two base angles are 72 degrees each.
Step-by-step explanation:
3:2 because 18/12 and 30/20 both reduce to 3/2

Answer:
r = -14
Step-by-step explanation:
3 = r + 17
r + 17 = 3
r + 17 - 17 = 3 - 17
r = -14
C. $147.50
the first 10 suits would sell at 250 each totaling 2500 which means he earns 5% of $2500, which is 0.05 x 2500 = $125. The next 3 suits which also sold at 250 which totals $750, he makes 3% of that amount which is 0.03 x 750 = $22.50. Together is makes 125 + 22.50 = $147.50 in commission.
