Answer:

D) 30

Step-by-step explanation:

L and V are the same so you have to rotate triangle LMN so that L points up like V. Next look at the hypotenuses, they are 40 and 24. set them up it a proportion like so 40/24. Then simplify to get 5/3. Now you multiply that by 18 to find the missing side with is 30.

If you can make my answer the brainliest that would be much appreciated. Thanks!

Semenov [28]

<h3>The measure of third angle of triangle is 67 degrees</h3>

<em><u>Solution:</u></em>

Given that,

The support of a wood table are in the shape of a right triangle

Since it is a right angle, one of the angle must be $90^{\circ}$

The measure of one of the angles is 23 degrees

To find: third angle angle

We know that,

Sum of all angles in triangle equals 180 degrees

Therefore,

$90^{\circ} + 23^{\circ} + \text{ third angle } = 180^{\circ}\\\\ \text{ third angle } + 113 = 180\\\\ \text{ third angle } = 180 - 113\\\\ \text{ third angle } = 67^{\circ}$
