The value of D should be 4
This is simple simplifying. If you need an explanation dm me.
here is the answer
x=-5
Answer:
the constant rate of change is 20
Answer:
4:12 6:18 :) I hope this is ok (I haven't done ratios in a while lol)
The hypotenuse is 6. 30-60-90 triangles have a ration of x, x

, and 2x, respectively. So since you have the value for the 30º side, then you just double it to get the hypotenuse's value.
