Ineed with this question what is the value of x? x = explain your answer .

The three sides of the triangle are equal and thus this is an equalateral triangle with 3 of the same angles. Thus angle LNM and NML are the same!

we can now make an equation

7x-3 = 11y + 5

Hmm, but we have two unknowns :/

We know that all triangles must add up to 180o so with 3 angles we get each angle to 90o!

Thus we dont even need the first equation (unless we needed it for something else)

so 90 = 7x - 3

7x = 93

x = 13.29

Your answer will be
