AFB is acute. DFB is obtuse. Finally CFD is right. And those are the"right answers" and your welcome hope you get a 100%
AFB = 48 degrees
DFB = 138 degrees
CFD = 90 degrees
In order to find AFB, we can see that AFC is equal to 90. We then subtract the 42 degree angle on the inside of it.
90 - 42 = 48
For the DFB angle, we know that we have a 90 degree angle plus the 42 degree angle. So we add them together.
90 + 42 = 132
Lastly CFD is a right angle and therefore is equal to 90.

Answer:
27%
Step-by-step explanation:
15.6 - 11.4 = 4.2
4.2 ÷ 15.6 = .27
.27 = 27%
First find the law
8.6-1.4n
so, 64th is 8.6-1.4x64
I think is -81
No her estimate is to low because if you multiply 15.5 by 12 you get 186
I think the answer is 12 cause you have to add
Step-by-step explanation:
x² + 4x - 9
= (x + 2)² - 13
a = 2, b = -13.
