If △NMO ∼ △XYZ, and the area of △NMO is 147 square feet, find the area of △XYZ

sladkih [1.3K]

The area of △XYZ according to the figure is 363ft²

<h3>Area of triangles</h3>

The formula for calculating the area of a triangle is expressed as:

A = 0.5bh

b is the base
h is the height

<h3>Calculate area of each triangles</h3>

For the triangle △NMO

Area of △NMO = 0.5bh

147 = 0.5b(14/12)

147 = 7b/12

7b = 12 * 147

b = 252

b = 252ft

b = 3024in

Get the base of △XYZ

14/3024 = 22/XZ

XZ = 4,752in

Area of △XYZ = 0.5 (4,752)(22)

Area of △XYZ= 52,272in²

Area of △XYZ = 363ft²

Hence the area of △XYZ is 363ft²

Solve for y. Please help!!

Nadya [2.5K]

Answer:

$y=3\sqrt{7}\ units$

Step-by-step explanation:

see the attached figure with letters to better understand the problem

we know that

In the right triangle ABD

$tan($

In the right triangle BCD

$tan($

remember that

m< BAD=m<CBD

therefore

$tan($

equate the equations

$y/9=7/y$

$y^{2}=63$

$y=3\sqrt{7}\ units$
