Answer:
78°
Step-by-step explanation:
Angles on a straight line = 180°
AD is the straight line
Angle BFA = 48
Angle CFD = 54
54 + 48 = 102
180 - 102 = 78
Therefore, Angle BFC = 78°
Answer:
1.03309 × 10^4
Step-by-step explanation:
First, move the decimal 4 times to the left in the number. This is so that m = 1.03309 is greater than or equal to 1 but less than 10.
Then, since the decimal was moved to the left, the exponent n is positive
n = 4
Write in the scientific notation form, m × 10n
= 1.03309 × 10^4
Hope this helps you out!
So I work this out on a sheet of paper and I'm pretty sure I did this right.
