Answer 1

7x - 3 = 60
7x = 63
  x = 9

answer
x = 9

Answer 2

Answer:

x = 9 and y = 5

Step-by-step explanation:

From the given figure :

In ΔLNM ,

LN = NM = LM

This shows that all the sides of the triangle are given to be equal.

And the triangle whose all sides are equal is called equilateral triangle and in an equilateral triangle the measure of its each angle is 60°

⇒ ∠L = ∠N = ∠M = 60°

Now, ∠N = 60°

⇒ 7x - 3 = 60

⇒ 7x = 63

⇒ x = 9

Also, ∠M = 60°

⇒ 11y + 5 = 60

⇒ 11y = 55

⇒ y = 5
