3² + 7 - y² - 5 - 2y² -1
= -3y² + 9 + 1 = -3y² + 10
The value of x is 12. The angles are supplementary and add up to equal 180. Solve for x and you'll get 12. Hope this helps!
Answer:10.2 inches
Step-by-step explanation:
we know that
In this problem we have two cases
First case
The given lengths are two legs of the right triangle
so
Applying the Pythagoras Theorem
Find the length of the hypotenuse
substitute
Second case
The given lengths are one leg and the hypotenuse
so
Applying the Pythagoras Theorem
Find the length of the other leg
substitute
Find the difference between the two possible lengths of the third side of the triangle
so
