To find out the thickness of each book you would have to divide 135 inches by 60 to get 2.25 .
135 ÷ 60 = 2.25
so the answer would be A
Answer:
x = -7
Step-by-step explanation:
7x-3 - 2x = -38
7x -2x = -38+3
5x = -35
x = -35/5
x = -7
Sorry but I’m lost what are you talking about
Answer:
57
Step-by-step explanation:
the sum of those two interior angles is equal to the exterior (116), so y = 15 and the measure of angle A is 57 if you plug it in
4) x + x + x = 180°
An equilateral triangle has three sides of equal length. Its interior angles are also equal. Since interior angles of a triangle should sum up to 180°, then each angle is 60°, making each angle congruent with one another.
So if x is equal to one angle and triangles have three angles then,
x + x + x = 180°
or 3x = 180°
