Answer:
2. one angle is 108, and other is 72
3. x is 12
Step-by-step explanation:
the ratio is 3:2.
3x + 2x = 180
5x = 180
x = 36
36 x 3 = 108
36x 2 = 72
so that is why the two angles re 108and 72.
for the last question, 37 plus 41 plus x = 90
37 plus 41 is 78
90 - 78 = 12
so that is why x is 12.
Answer:
$39.10
Step-by-step explanation:
$40 * 1.15 = $46
$46 * 0.85 = $39.10
If you would like to solve the equation 9/11 = x/22, you can calculate this using the following steps:
9/11 = x/22 /*22
x = 9/11 * 22
x = 18
The correct result would be 18.
