Answer 1

Answer: You have a triangle with equal sides, which means it is an equilateral triangle. This also means that all the angles of the triangle are equal, and they add up to 180 degrees.

To find the value of x, you need to set the expressions for the angles equal to each other and solve for x. For example, you can write:

(7x - 3)° = (11y + 5)° = (x)°

Since all the angles are equal, you can choose any two of them and solve for x. For example, you can write:

(7x - 3)° = (x)°

Then, you can simplify the equation by subtracting x from both sides and adding 3 to both sides:

6x = 3

Finally, you can divide both sides by 6 to get x:

x = 3 / 6 x = 0.5

Therefore, the value of x is 0.5. You can check your answer by plugging it into the expressions for the angles and seeing if they are equal. For example:

(7 × 0.5 - 3)° = (0.5)° (3.5 - 3)° = (0.5)° 0.5° = 0.5°

This is true, so x = 0.5 is correct.

I hope this helps you solve your math problem.

Answer 2

`\sf x =\boxed{ 9}`

Explanation:

An equilateral triangle is a triangle in which all three sides are equal in length and all three angles are equal in measure. Equilateral triangles are also known as regular triangles.

In this case:

The given triangle LMN is equilateral triangle.

So, three angles are equal all of them are 60°.

We have

∠L = ∠M = ∠N = 60°

So,

∠N = 60°

Substitute the given value:

(7x - 3)° = 60°

7x - 3 = 60

Add 3 on both sides.

7x - 3 + 3 = 60 + 3

7x = 63

Divide both sides by 7.

`\sf (7x)/(7)=(63)/(7)`

`\sf x =\boxed{ 9}`

Therefore, the value of x is 9.
