Answer:
Step-by-step explanation:
To find the value of y, you can create an equation where two parts of the line are equal to the whole line:
Substitute given values:
Solve for y. Simplify parentheses:
Combine like terms to simplify the equation:
Get the variable on one side of the equation and the constants on the other. Add 9 to both sides:
Subtract 9y from both sides:
Isolate the variable. Divide both sides by 10:
The value of y is 2. Insert this value into each line segment value and solve:
:Done
You can check by using:
This statement is true, so the values are correct.
It is B because √2 can not be it a fraction and because √2 cannot be broken down rationally into a rational number such as √9

Step-by-step explanation:
huesenlig h 40°. ΜΑ. Which equation could be used to find the measure of ... base of a 350-foot-tall building. In right triangle ABC shown below, AC 729 inches, AB The angle of elevation from a person to.
The correct answer is option B which is we need ∠L ≅ ∠R to prove congruency.
<h3>What is congruency?</h3>
The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.
According to the SAS theorem which means Side Angle Side, The angle which is included between the two sides must be congruent.
Here we are given that
KL = NR
JL = MR
Now in the figure, we can clearly see that the angle included between JL & KL is L & the angle included between NR & MR is R.
So for the triangles to be congruent by SAS, angle L must be congruent to angle R.
∠L=∠R
Therefore the correct answer is option B which is we need ∠L ≅ ∠R to prove congruency.
