Answer: hope this helps
Step-by-step explanation: 360
Triangles ABD and BCD are similar, because they are both right and share a common angle, and thus all three angles are equal.
This means that we can set the proportion

Plug the numbers and we have

Solve for
:

All work is shown in picture below.
Answer:
graph of h(x)= a slope of 2, and the y-intercept is 0.
graph of g(x)= a slope of 1, and a y-intercept of 6.
graph of f(x)= a slope of 1, and a y-intercept of -6.
Step-by-step explanation:
The equation would be h(x)=(x-6)+(x+6) which is also equal to h(x)= 2x if you combine like terms. f(x) and g(x) equations are pretty straight forward.
