Answer:
The answer to your question is:
Step-by-step explanation:
Data
a)
C (0, 0)
D (7, 12)
m = (12 - 0) / (7 - 0)
m = 12/7
Slope = 12/7
b)
(y - y1) = m(x - x1)
(y - 12) = 12/7 (x - 7)
y - 12 = 12/7 x - 1
y = 12/7 x - 1 + 12
y = 12/7 x + 11
c)
Domain [0, 7]
Range [0, 12]
Answer:
y=34, x=17 root 3
Step-by-step explanation:
30 60 90 triangle.
Shortest side is x, hypotenuse is 2x, bottom length is x root 3
This can be solved using the
angle bisector theorem. Note that line segment AD is the angle bisector of triangle DAB from angle DAB. Therefore, we know that the ratios

and

are equal. Solving, we get

. Cross multiplying, we get

, and solving this equation we get

.
