(fog) (x) = (5x - 7) / (5x - 4)
The denominator cannot be zero so the domain is All real x except x = 4/5
It is a right angled triangle
The angles in every triangle have to add up to 180, as two of the angles are 60 and 30 the third angle has to be 90
Hope this helps :)
Answer:
18
Step-by-step explanation:
We will try to find the angle on the left side of the small triangle. So we have to use Tan.
SOHCAHTOA
TanФ = 12/8
= 12/8 = 56.31°
So the other one is 33.69° It's the top left one of the smaller triangle.
The top right side of the bigger triangle is 56.31 because they both add up to make 90°
Now that we have an angle of the bigger triangle we will find the x.
Tan 56.31 = x/12
x = 18
Theres probably a easier way but i dunno
Answer:
Im pretty sure it is 17
