True: A face of a polyhedron is simply a flat boundary that helps forms the 3D solid.
3.That BC are congruent and that AB and AC are congruent as well
of right angle triangle! .
<u>Step-by-step explanation:</u>
Here we have , A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 32 centimeters, and the length of the other leg is 25 centimeters. The student incorrectly says that the length of the hypotenuse is 7.5 centimeters. We need to find:
A)
We have , One length as 32 cm and other as 25 cm , as

By Pythagoras Theorem ,
⇒ 
⇒ 
⇒ 
⇒ 
So ,
of right angle triangle! .
This is equivalent to finding a function g in which

.
We simply reverse the actions of the initial function by adding 81 back and taking the square root. Therefore,

.
