Fyi I didn't find this on google or anything I did the calculation on my computer and yes this is correct...
If it's wrong I'm sorry...
Answer:The function is nonlinear
Step-by-step explanation:
7.32a + 2.1(2.7 -18a)
7.32a + 5.67 - 37.8a (multiply 2.1 to 2.7 and 18a)
5.67 - 30.48a (combine 7.32a and -37.8a since they are like terms)
Answer:
<h2>Angle ADF is equal to 52° and angle FDC is equal to 38°.</h2>
Step-by-step explanation:
In the image attaches, you can observe that angles ADF and FDC are complementary angles, because they sum 90°.
![\angle ADF + \angle FDC = 90\°](https://tex.z-dn.net/?f=%5Cangle%20ADF%20%2B%20%5Cangle%20FDC%20%3D%2090%5C%C2%B0)
And we know that
![\angle ADF=2x\\\angle FDC = x+12](https://tex.z-dn.net/?f=%5Cangle%20ADF%3D2x%5C%5C%5Cangle%20FDC%20%3D%20x%2B12)
Replacing these expressions, we have
![2x+x+12=90\°\\3x=90\° - 12\°\\x=\frac{78}{3}\\ x=26](https://tex.z-dn.net/?f=2x%2Bx%2B12%3D90%5C%C2%B0%5C%5C3x%3D90%5C%C2%B0%20-%2012%5C%C2%B0%5C%5Cx%3D%5Cfrac%7B78%7D%7B3%7D%5C%5C%20x%3D26)
Then, we replace this value in each expression to find both angles measures.
![\angle ADF= 2(26)=52\°\\\angle FDC = 26+12=38\°](https://tex.z-dn.net/?f=%5Cangle%20ADF%3D%202%2826%29%3D52%5C%C2%B0%5C%5C%5Cangle%20FDC%20%3D%2026%2B12%3D38%5C%C2%B0)
Therefore, angle ADF is equal to 52° and angle FDC is equal to 38°.
I can’t see the photo so I can’t tell you the answer but good luck. Congruent means they look the same I think.
