Answer: 60 square inches
Step-by-step explanation:
25% is .25 so... multiply .25 by 56 and get 14 hope this helps :D
B. 180cm3
You have to find length, width, and height of both objects.
For the first one multiply:
3 x 8 x 5 = 120
Then multiply:
2 x 5 x 6 = 60
Add them together:
120 + 60 = 180cm3

<2 and <6 are right angles by the definition of perpendicular lines.
Since corresponding angles are congruent, m || n.
11.
In a triangle, the measures of the three angles add to 180 degrees.
If one angle is a right angle, then that angle measures 90 degrees. The other two angle measures plus 90 degrees add to 180 degrees, so the other two angle measures add to 90 degrees. In a right triangle there is a right angle and two other angles that are complementary.
Now look at your problem.
One angle is a right angle.
The other two angles are complementary, so their measures add to 90 deg.
8x + 2 + 9x + 3 = 90
17x + 5 = 90
17x = 85
x = 5
