In the figure, VW || YZ. Find the value of x, and the measure of YA and WA.

svetoff [14.1K]

Step-by-step explanation:

because VW || YZ, the 2 triangles are similar.

this is given by the rules of equal angles of intersecting lines with parallel lines. Z to V and Y to W would be such intersecting lines.

and therefore, the angle at W is the angle at Y, the angle at V is the angle at Z. and therefore both angles at A are equal.

so, for similar triangles the scaling factor between corresponding pairs of sides is the same for all sides.

e.g. the same scaling factor that converts 7.2 to 12, converts then also x to x+4.

7.2 × f = 12

f = 12/7.2 = 12/ 72/10 = 120/72 = 10/6 = 5/3

x × 5/3 = x + 4

5x = 3x + 12

2x = 12

x = 6

A to Y = x = 6

W to A = x + 4 = 6 + 4 = 10

Phantasy [73]

Answer:

Keith live 280 miles far way from the mountains.

Step-by-step explanation:

Consider the provided information.

Keith drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 8 hours.

Let the distance is D and average rate or speed is x miles.

$Distance =Speed\times Time$

Substitute the respective values.

$D=x\times 8\\D=8x$

When Keith drove home, there was no traffic and the trip only took 5

hours. The average rate was 21 miles per hour faster on the trip home,

The average rate or speed during return is x+21 miles.

Substitute the respective values in the above formula.

$D =(x+21)\times 5\\D=5x+105$

Equate both the equations.

$5x+105=8x\\3x=105\\x=35$

Substitute the value of x in $D=8x$

$D=8(35)\\D=280$

Hence, Keith live 280 miles far way from the mountains.
