In a right triangle, the measure of one acute angle is 12 more than twice the measure of the other acute angle. Find the measure
soldi70 [24.7K]

Given:

In a right triangle, the measure of one acute angle is 12 more than twice the measure of the other acute angle.

To find:

The measures of the 2 acute angles of the triangle.

Solution:

Let x be the measure of one acute angle. Then the measure of another acute is (2x+12).

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees. So,

x+(2x+12)+90=180

3x+102=180

3x=180-102

3x=78

Divide both sides by 3.

x=\dfrac{78}{3}

x=26

The measure of one acute angle is 26 degrees. So, the measure of another acute angle is:

2x+12=2(26)+12

2x+12=52+12

2x+12=64

Therefore, the measures of two acute angles are 26° and 64° respectively.

Find YW. YW = _<br><br> I just need the answer for YW no explanation needed.
KATRIN_1 [288]

Answer:

YW=20\ units

Step-by-step explanation:

we know that

In a parallelogram the diagonals bisect each other

The figure XYZW is a parallelogram

so

VW=VY

VX=VZ

<em>Find the value of b</em>

VW=VY

substitute the given values

b+8=5b

solve for b

5b-b=8\\4b=8\\b=2

Find the length of YW

YW=YV+VW ----> by addition segment postulate

YW=5b+b+8

substitute the value of b

YW=6(2)+8=20\ units
