Given:

A figure of a right triangle with perpendicular 500 m  and hypotenuse x.

To find:

The value of x.

Solution:

If a transversal line intersect two parallel lines, then alternate interior angles are congruent.

Using the above definition the measure of angle opposite to the perpendicular is 40 degrees.

In a right angle triangle,

\sin \theta =\dfrac{Perpendicular}{Hypotenuse}

In the given triangle,

\sin 40^\circ =\dfrac{500}{x}

x=\dfrac{500}{\sin 40^\circ }

x=\dfrac{500}{0.6427876}

x=777.8619

Round the value to the nearest tenth.

x\approx 777.9

Therefore, the value of x is 777.9 m.

Yakvenalex [24]
Given:
Triangle:
height = 6ft
base = 4ft

Rectangle:
length = x
Width = 6 ft

Surface Area = 150ft²

Area of a Triangle = h*b / 2 = (6ft * 4ft) / 2 = 12ft²

Area of a rectangle = Surface Area - Area of a Triangle
A = 150 ft² - 12 ft² = 138 ft²

138 ft² = x * 6ft
138 ft² / 6 ft = x
23 ft = x.
