Question

Find the value of X to the nearest tenth. 39.0 60.0 15.5 31.0

Answer 1

$\dfrac{2x}{39}=\dfrac{62}{39+39}\\\\\dfrac{2x}{39}=\dfrac{62}{78}\ \ \ \ |cross\ multiply\\\\2x\cdot78=39\cdot62\\\\156x=2418\ \ \ \ |divide\ both\ sides\ by\ 156\\\\\boxed{x=15.5}$

Answer 2

Answer:

$x=15.5$

Step-by-step explanation:

We are given with the diagram with mid segment in a triangle

If we have a mid segment in a triangle and it is parallel to the other side then we use formula

mid segment = half of base of the triangle

$2x= \frac{1}{2} * 62$

$2x= \frac{62}{2}$

$2x=31$

Divide both sides by 2

$x=15.5$

The value of $x=15.5$
