Answer:
The answer is in the explaination
Step-by-step explanation:
A + B = 180 degrees
14x - 72 = 180
14x = 108
x = 8
A = 5 times 8 plus 20
A = 60
Answer:
Step-by-step explanation:
100% divided by 4 is 25%
25 books were 1/4 of the books total.
the other 3/4 would be 75%
they og ordered 100 books
Angle 45
Because it could be 45,45,90
Answer:
35.8 deg
Step-by-step explanation:
a/sin A = b/sin B
24/sin x = 39/sin 71.8
sin x = (24 * sin 71.8)/39
sin x = 0.584598
x = sin^-1 0.584598
x = 35.8 deg
