Answer:

True the triangle is a right triangle.

Step-by-step explanation:

the Pythagorean Theorem states that a^{2} +b^{2} =c^{2}

so,

85^{2} =7225\\77^{2} =5929\\36^{2} =1296\\5929+1296=7225

damaskus [11]

Hey there!

Step By Step:

Well so we know that 12 is about half of an 25. So what we are gonna do is to buy 3 of 12$ and 2 of 25$.

3x12=36 and 2x25=50.

With adding those two last numbers, you’ll get $86.

Graph would be down below.

Hope it helps :D
