What theorem or postulate can you use to determine a relationship between these two angles? Solve for x.

1 answer:

4 0

It's the consecutive interior angles theorem; it goes like this:

95° = (2x + 5)°
90° = 2x
45° = x

Basically it says the alternate interior angles of two parallel lines that are cut by a transverse line are equal/the same.

Tennis racket marked up 50% to $36.76

Kaylis [27]

I asssume we want to find the original price
so marked up 50% means if original price=100, then marked up price=50+100=150%

so
36.76=150%
hack, since 150=3 times 50 and 2 times 50=100, divide 36.76 by 3 then mutiply by 2

36.76=150%
divide both sides by 3
12.25333333333=50%
multiply both sides by 2
24.5=100%
original price=$24.50

4 1/5 + 2 5/6 = ? 6 1/6 6 1/30 7 1/4 7 1/30

grigory [225]

Answer:

7 1/30

Step-by-step explanation:

4 1/5 + 2 5/6

Get a common denominator of 30

4 1/4 = 4 1/5*6/6 = 4 6/30

2 5/6 *5/5 = 2 25/30

4 6/30 + 2 25/30
