Select all pairs of alternate exterior angles. Assume the lines are parallel.

1 and 8

2 and 7

Step-by-step explanation:

Alternate angles take form of a Z-angle.

For alternate exterior angles look for exterior angles that for Z- pattern.

The alternate exterior angles are marked in the attached diagram.

Hence the alternate exterior angles are:

1 and 8

2 and 7

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
