They are adjacent angles but there are other options that I can't remember off the top of my head

Vertical angles share a vertex, and have the same lines for sides, but do not have a side in common. Angles ACB and BCD have side BC in common, so cannot be vertical angles.

Angles ACB and ECF are vertical angles.

_____

There is no vertical angle in the diagram corresponding to ∠BCD, as ray CD is not part of a line that passes through point C.

−4/9f = −3 what does f equal?

solmaris [256]

Answer:

$\frac{27}{4}$ or 6.75

Step-by-step explanation:

To cancel out a fraction you multiply by the reciprocal. To make multiplying easier you can make -3 into a fraction by putting 1 under it
Multiplying across, two negatives make a positive so the answer is positive

$(-\frac{9}{4})-\frac{4}{9}f=-\frac{3}{1} (-\frac{9}{4})$

$f=\frac{27}{4}$

I don't know how to do this question.

The perimeter is the measure around the shape, so just add all the sides together-
6+5x+x+2
6x+8
Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2
6(x+2)
6x+12
/2
3x+6
