Answer:
72 and 36
Step-by-step explanation:
Since it is an isosceles triangle we know that one of the angles will be 72 degrees as well. I added both of the 72s and got 144. A triangle has 180 degrees. Subtract 144 from 180 and you get 36.
Answer:
B) $23.45
C) $157.50
A + B + C = $330.95
Step-by-step explanation:
$6.70 × 20 = $137 17.5% of $137 = $23.45
45c × 350 = $157.5
$150 + $23.45 + $157.50 = 330.95
Answer:
r = - 6
Step-by-step explanation:
Given
6r + 7 = 13 + 7r ( collect terms in r on the left and numbers on the right )
Subtract 7r from both sides
- r + 7 = 13 ( subtract 7 from both sides )
- r = 6 ( multiply both sides by - 1 )
r = - 6
