How do you classify a pair of angles?

Adjacent Angles
Adjacent angles are a pair of angles that share a side and a vertex but do not overlap.

Complementary angles
Complementary angles are a pair of angles that add up to 90o. Placing complementary angles together forms a right angle.

Supplementary angles
Supplementary angles are a pair of angles that add up to 180o. Placing supplementary angles together forms a straight line.

Corresponding angles
Corresponding angles are formed when a pair of parallel lines is intersected by a third line (also called a transversal line). They are a pair of angles that are at corresponding positions but are not adjacent angles. Corresponding angles are on the same side of the transversal line and always have the same degree measurement.

Alternate interior angles are formed when there exists a transversal. They are the angles on opposite sides of the transversal, but inside the two lines the transversal intersects. Alternate interior angles are congruent to each other if (and only if) the two lines intersected by the transversal are parallel.

An easy way of identifying alternate interior angles is by drawing the letter "Z" (forwards and backwards) on the lines as shown below.

answer: finding the extract measurements and knowing the points

step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
