Answer:

450 feet at ground level

Step-by-step explanation:

The width of the bridge at ground level will be where the function intercepts the x-axis also known as the roots or zeros of the function. They are found using the zero product property to set each factor equal to 0.

This means (x-225) = 0 and (x + 225) = 0. So x = -225, 225.

This means the width is the absolute value of |-225| + 225 since distance cannot be negative. This makes it 450 feet.

Find the value of x in the given figure of a triangle
Luba_88 [7]

In the triangle ABE

step 1

Find out the measure of angle AEB

m by form a linear pair

mm

step 2

Find out the measure of angle ABE

m by alternate interior angles

step 3

Find out the measure of angle x

Remember that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

msubstitute given values

x+100+30=180

x=180-130

<h2>x=50 degrees</h2>
