Step-by-step explanation:
16. Two parallel lines are cut by transversal. Angles with measures
and
are alternate exterior angles. By alternate exterior angles, the measures of alternate exterior angles are the same:

Then

17. Two parallel lines are cut by transversal. Angles with measures
and
are alternate interior angles. By alternate interior angles, the measures of alternate interior angles are the same:

Then

18. Two parallel lines are cut by transversal. Angles with measures
and
are alternate exterior angles. By alternate interior angles, the measures of alternate exterior angles are the same:

Then

19. The diagram shows two complementary angles with measures
and
. The measures of complementary angles add up to
then

Hence,

Check:

20. Angles
and
are vertical angles. By vertical angles theorem, vertical angles are congruent, so

Hence,

21.
and
are supplementary. The measures of supplementary angles add up to
so

Therefore,

Answer:
2x^2 - 3x - 1
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
using the pythagorean theorem, c^2=a^2+b^2
5^2=x^2+4^2, x=3
Answer:
-2
Step-by-step explanation:
sustitue -4 into x for 3-x which would equal 7 because a negative times a negative equals positive. Then substitue 1 in for x in -4x-5 which would get you -9

Answer:
So Average Price of horse is $360
Step-by-step explanation:
Given:
25 horses sold in January for $ 2500
25 horses sold in February for $10500
TO find:
Average price of horse = ?
Solution:
Average price is usually found out by adding all the values and dividing by its total no of values
Now in our case
Total Horse = 25 + 25
= 50
Total Money = $7500 + $10500
= $18000
Average Price 
Average Price 
=$360
So Average Price of horse is $360
