Answer:

Step-by-step explanation:

▪Picture 1. x = 28

$\frac{x}{42} = \frac{10 + x}{57} \\ 42(10 + x) = 57x \\ 420 + 42x = 57x \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: - 42x = - 42x}{ \frac{420}{15} = \frac{15x}{15} } \\ \\ 28 = x$

▪Picture 2. I don't know what in trying to solve.

▪Picture 3.

•ABC = 50

•DEF = 95

•GHI = 65

(20 points!) In triangle RSW, line segment RW is a median and is equal to 27 cm. What is the length of RX?

Fofino [41]

Answer:

Option D. 18 cm

Step-by-step explanation:

we know that

A <u><em>centroid</em></u> of a triangle is the point where the three medians of the triangle meet.

A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

The centroid divides each median in a ratio of 2:1

In this problem the centroid of triangle RST is the point X

$\frac{RX}{XW}=\frac{2}{1}$

$RX=2XW$ -----> equation A

$RX+XW=27$ -----> equation B

substitute equation A in equation B

$2XW+XW=27$

Solve for XW

$3XW=27$

$XW=9\ cm$

Find the value of RX

$RX=2XW$ ----- $RX=2(9)=18\ cm$
