W and Z are both 30
because angles on a straight line = 180, the line diagonally top left to bottom right has an intersecting line with angle of 150.

180-150 = 30

this leaves angle Y which is 90-30 as it is a right angle. So angle Y is 60 and to get x, it is 90 due to the right angle. you can prove this by saying angles on a straight line are 180 and 180-(Y+ Z) or 180-(30+60)

Two cars, 540 kilometers apart, begin driving toward each other on a long, straight highway. one car travels 75 kilometers pe

Elodia [21]

One car travels at a speed of 75 kilometers per hour and the other car travels at a speed of 105 kilometers per hour.

Since both the cars are travelling towards each other their combined speed will be: 75+105=180 km/h.

Now, since the distance between the cars to start with is 540 km. Therefore, the time taken before the cars collide is:

$t=\frac{540}{180} =3$ hours.

Now, the speed of the canary is 100 km/h.

Therefore, the Canary flies flies for (100 km/h)x(3 hours) = 300 km before the cars collide.

2x + By = 15

We solve for y to put the equationj in the y = mx + b form in which b is the y-intercept.

By = -2x + 15

y = -2/Bx + 15/B

The y-intercept is 15/B, and we are told the y-intercept is 5.

15/B = 5

15 = 5B

B = 3
