Write a list of steps that are needed to find the measure of angle B (There are only 180 degrees in a triangle so that wouldn't work.113 degrees is the measure of angle BCD which is outside of the triangle. Use the idea of supplementary angles to calculate the measure of angle BCA. Then you calculate the measure of angle B using the idea that the three angles inside of a triangle have to add up to 180 degrees)

what do you need me to answer?

step-by-step explanation:

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

the first option is the answer.

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
