Select the correct answer.

transversal t cuts parallel lines r and s as shown in the diagram. which theorem does the diagram illustrate?

a.
alternate interior angles theorem

b.
alternate exterior angles theorem

c.
same-side interior angles theorem

d.
corresponding angles theorem

Step-by-step explanation:

Let name the marked angles in the figure as x and y

Given that : x = y

So, to state which theorem does the diagram illustrate, we first need to find the relation between the angles x and y

Alternate interior angles : The angles which lie interior to the parallel sides but on the opposite side of the transversal.

But x and y lie exterior to the parallel lines, So this option is rejected.

Alternate exterior angles : The angles which lie exterior to the parallel sides but on the opposite side of the transversal.

But x and y lie exterior to the parallel lines, So this option is correct.

Same side interior angles theorem : This theorem states that the sum of same side interior angles in 180.

So it can't be said angle x = angle y by using this theorem. So, this option is rejected

Corresponding angles theorem : The angle which lie at same relative position of the transversal.

But, angle x and angle y lie on the opposite side. So, this option is rejected

So, B. Alternate Exterior angles theorem

Also, next time including the diagram would be very helpful.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
