Question

find the value of x.
I Need to show the equations please, and show my work

Answer 1

Answer:

15

Step-by-step explanation:

since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as

13+x+4x+2=90

add the x variables together and the constants separately

15+5x=90

then subtract 15 from both sides.

15+5x=90

-15      -15

5x=75

then divide 5 from both sides.

75/5= 15

so x is 15 :).

Answer 2

Answer:

It shows a 90° angle split into 2 separate angles so,

$13 + x + 4x + 2 = 90\\\\5x + 15 = 90\\\\5x = 75\\\\x = 15$

Basically, the total angle measure of the given angles [90°, (13 + x)°, and (4x + 2°) equals 180°. Take away 90 from 180 and you get 90, then solve for x using what's left: 13 + x + 4x + 2 = 90. You get x = 15.
