Suppose M is the midpoint of FG. Find the missing measure.

Arlecino [84]

A midpoint divides a line segment into equal halves.

The value of x is 3.4

Given that:

$FG = 11x - 15.6$

$MG = 10.9$

Since M is the midpoint, then:

$FG = 2 \times MG$

So, we have:

$11x - 15.6 =2 \times 10.9$

$11x - 15.6 =21.8$

Collect like terms

$11x =15.6 +21.8$

$11x =37.4$

Solve for x

$x =3.4$

<em>Hence, the value of x is 3.4</em>

Solve for x. Round to the nearest tenth of a degree, if necessary.

MissTica

Answer:

x ≈ 54.8°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = $\frac{opposite}{adjacent}$ = $\frac{PQ}{QR}$ = $\frac{7.1}{5}$ , then

x = $tan^{-1}$ ( $\frac{7.1}{5}$ ) ≈ 54.8° ( to the nearest tenth )
