The measure of angle AFB = 78°

Answers

Answer: is C

Step-by-step explanation: you have a 90 so 90-78 is 12

The answer is 12

We know that angles AFB and CFD and BFC sum up to 180

Using this information we can write the equation

AFB + CFD +BFC = 180

Now substitute known values:

78 + 90 (it is a right angle) + BFC = 180

Now solve-
You should get

pls answer all 3 parts

Answers

Answer:

a. 14

b. 1

c. 2

Step-by-step explanation:

If there are 4 one point questions and 5 two point questions, then 5 multiplied by two is 10 and adding it to 4 is 14. The quiz would be 14 points total. If you scored 87.5% on the quiz then you would know that you got 12 of the questions correct and you would know that by finding 87.5% of 14 which the equation to do so would be 87.5/100= 0.875, then 0.875* 14= 12.25. If you round 12.25 to the nearest whole number then it's 12. And since you got all the 1 point questions right, then you must of gotten 1 two point question wrong.
