Answer:
132
Step-by-step explanation:
Alternate angles are equal. Therefore, A = B.
<u>Find x</u>
5x - 18 = 3x +42
2x = 60
x = 30
<u>Substitute x in angle A</u>
5(30) - 18 = 132
Okay so I did this:
$10.20*40 + $1.30= $409.3
$10.20*38 + $1.30 = $388.9
$409.3+$388.9= $798.2
Hope it helped!
Answer:
x = -
Step-by-step explanation:
Given
(x - 9) = - 11
Multiply both sides by 3 to clear the fraction
2(x - 9) = - 33 ← distribute left side
2x - 18 = - 33 ( add 18 to both sides )
2x = - 15 ( divide both sides by 2 )
x = -
