Ocean waves move in parallel lines toward the shore. the figure shows the path that a windsurfer takes across several waves. for this exercise, think of the windsurfer's wake as a line. if m∠1 = (7x + 4y)° and m∠2 = (7x + y)°, find x and y.

The value of x is 10 and the value of if y is 8.

Explanation:

First mark the angles 3, 4 and 5 as shown in below figure.

If a transversal intersects the two f three parallel lines, the corresponding angles are always equal.

From the figure is noticed that the angle 3, 5 and 2 are corresponding angles.

It is given that the angle 3 is 78 degree. So,

Since the angles 1 and 5 are supplementary angles, therefore there sum is 180 degree.

It is given that and

           .....(2)

Subtractact equation (2) form equation (1).

Therefore, the value of x is 10 and the value of if y is 8.
