The first answer in the choices
Answer:
x=8
Step-by-step explanation:
7x-6+60+70=180°
7x-6+130=180°
7x+124=180°
7x=180-124
7x=56
x=56

<em><u>The equations used to find the length of leg of triangle are:</u></em>

<em><u>Solution:</u></em>
From given,
Area of right triangle = 24 square feet
Also from given figure in question (attached below )
base = x and height = x + 2
<em><u>The area of triangle is given by formula:</u></em>

Substituting the values we get,

<em><u>Also, the above equation can be written as,</u></em>

<em><u>Thus the equations used to find the length of leg of triangle are:</u></em>

-3x + 20 > = 8
-3x > = 8 - 20
-3x > = -12
x < = -12/-3
x < = 4
