The maximum height of a vehicle that can safely pass under a bridge is 12 feet 5 inches. a truck measures 162 inches in height. which best explains whether or not the truck can pass safely under the bridge? the truck can pass safely under the bridge. the truck is 13 inches shorter than the maximum height. the truck cannot pass safely under the bridge. the truck is 13 inches taller than the maximum height. the truck can pass safely under the bridge. the truck is 12 inches shorter than the maximum height. the truck cannot pass safely under the bridge. the truck is 12 inches taller than the maximum height.

answer:

what is your question that you ask

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
