One angle of a triangle is 20 more than the second. The measure of the third angle is twice the sum of the first two angles. Find the measure of the angles.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

a. she will receive a refund of $278.

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
