What is the value of x? enter your answer in the box. x = an equilateral triangle l m n with horizontal base m n and vertex l is above the base. sides l m and m n and n l are labeled with single tick mark. angle l n m is labeled as left parenthesis 7 x minus 3 right parenthesis degrees. angle l m n is labeled as left parenthesis 11 y plus 5 right parenthesis degrees.

x=9

Step-by-step explanation:

Since the triangle is an equilateral, we know that all sides, and in turn angles are equal. The interior angle for an equilateral triangle is 60 degrees. Since we are looking for what x equals, we plug the 60 into that equation.

7x-3=60

When solved, you get x=9.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
