If triangle VWZ is congruent to triangle XWY, find the length of YX.
valkas [14]

Answer:

Measure of side YX is 22 units.

Step-by-step explanation:

Since ΔVWZ ~ ΔXWY, their corresponding sides will be in the same ratio.

\frac{VW}{XW}=\frac{VZ}{XY}=\frac{WZ}{WY}

By substituting the values given in the picture in the ratio,

\frac{45}{30}=\frac{(3x-9)}{(x+8)}=\frac{36}{24}

\frac{(3x-9)}{(x+8)}=\frac{3}{2}

By cross multiplication,

2(3x - 9) = 3(x + 8)

6x - 18 = 3x + 24

(6x -18) + 18 = 3x + 24 + 18

6x - 3x = (3x + 42) - 3x

6x - 3x = 42

3x = 42

x = \frac{42}{3}

x = 14

m(YX) = x + 8

          = 14 + 8

          = 22

Therefore, measure of side YX is 22 units.

Susan began counting backwards from 1298 by 4's saying one number every 5 seconds. At the same time Jim begins counting forward
SpyIntel [72]
1298 - 4x =171 + 3x

Add 4x to both sides

1298 = 171 + 7x

Subtract 171 from both sides

1127 = 7x

Divide by 7 on both sides


x = 161

They will both say the number 161 at the same time.
