The correct answer is D!!
72 and 45 can both be divided by 3.
So,
72 + 45
= 3 (24 + 15)

You can find the perpendicular bisector of a line segment, but
there's no such thing as the perpendicular bisector of a triangle.
What does it mean to be perpendicular to a triangle ?
What does it mean to bisect a triangle ?
Answer:
y = √(3² + 3²)
9 = √(5² + x²)
Step-by-step explanation:
Diagram 1:
Hypotenuse = y
Opposite = 3
Adjacent = 3
y² = 3² + 3²
y = √(3² + 3²)
y = √(9 + 9)
y = √18
Diagram 2:
Hypotenuse ² = known leg² + unknown leg²
Hypotenuse = 9
Known leg = 5
Unknown leg = x
9² = 5² + x²
9 = √(5² + x²)
9² = 5² + x²
9² - 5² = x²
x² = 81 - 25
x = √ 56
