How Can You Tell If An Ordered Pair (x,y) Is A Solution Or A System Of Linear Equations?
Answer 2

Answer:

To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

The measure of angle JKL in the triangle JKL is 54°.

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

From the given figure line segments JM and ML are of equal measure as the line segment KM bisects JL and hence bisects the vertex angle.

Therefore,

2x + 5 = 3x - 6.

2x - 3x = - 6 - 5.

- x = - 11.

x = 11.

Now, m∠JKL = 2m∠JKM = 2m∠LKM.

So, m∠JKL = 2[2(11) + 5]°.

= 2(22 + 5)°.

= 2(27)°.

= 54°.
