Question

mixed exercises
$overline{jh}$ is a midsegment of $\triangle klm$. find the value of $x$.
13.
triangle klm with midsegment jh, side lm is 30, segment jk is x
14.
triangle klm with midsegment jh, segment jh is 9, segment lm is x

Explanation:

Step1: Recall midsegment theorem

The midsegment of a triangle is half the length of the side it is parallel to.

Step2: Solve problem 13

Set $x = \frac{1}{2} \times 30$
$x = 15$

Step3: Solve problem 14

Set $x = 2 \times 9$
$x = 18$

Answer:

1. $x=15$
2. $x=18$
