Answer:
d=15
Step-by-step explanation:
So in this question we are using the Pythagorean Theorem. a^2 + b^2 = c^2
The side opposite to the right angle is the hypotenuse.
So to solve the equation put in the values for a and b.
9^2 + 12^2 = c^2
81 + 144 = c^2
225 = c^2
Now take the square root of 225
= 15
so d = 15
