8p-8=-9(2p+5)-9(6-3p)
p=91
I showed the work up there and checked
The choose (C) 60
The measure of the angles of a triangle is 180, and this triangle is equilateral, so 180/3=60, each angle is 60°
Option: step 2.
Because the student divided only the right side by 2. If you divide one side by a number you have to do the same with the other side to maintain the equality.
The answer is b. You can find it by doing Pythagorean theorem. You know the radius and one side of the triangle, so now you solve for the other side by using that theorem. Once you have the length of the missing side you subtract it from the radius. (14.5 - 10.5).
Is this a true or false question? If so, then the answer is true.
