The measure of angle AFB = 78°

The Measure Of Angle AFB = 78
The Measure Of Angle AFB = 78

Answers

Answer 1

Answer: is C

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

Answer 2
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

180-168 which is 12

HELP WITH EQUATION

Answers

I think  the answer its 1.8 percent because if you subtract 15-13.2 comes out to be 1.8.

but l also think it could be 12 percent error.      

The odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is  [tex]12 \%[/tex] .

What is percentage ?

A percentage is a number or ratio that can be expressed as a fraction of 100. And is denoted using the percent sign, "[tex]\%[/tex]".

Percentage [tex]=\frac{Diffeerence \ in \ value}{Total \ value}[/tex]

We have,

Last trip to the hardware store [tex]=13.2[/tex] miles

Original trip to the hardware store [tex]=15[/tex] miles

So,

Using the above given formula;

Percentage error [tex]=\frac{Diffeerence \ in \ value}{Total \ value}*100[/tex]

                     [tex]=\frac{15-13.2}{15} *100[/tex]

                    [tex]=\frac{1.8}{15} *100[/tex]

                    [tex]=12 \%[/tex]

So, the Percentage error in the odometer is [tex]12 \%[/tex] which is find out using above given formula.

Hence, we can say that the odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is    [tex]12 \%[/tex] .
