First You add all given angles up to equal 180 to give you x then you plug x into equations
A= 125 degrees
C= 35 degrees
As x increases from 9 to 12 (a change of 3), y increases from -2 to 0 (a change of 2). Thus, the slope of this line is 2/3.
Subbing this info and the coordinates of one of the points into y = mx + b, we get:
-2 = (2/3)(9) + b. Solving for b: b = -2 -18/3 = -8. Then the equation of this line is:
y = (2/3)x - 8.
Check by subst.: Does (12,0) satisfy this equation? 0 = (2/3)(12) - 8? Yes.
Let
x = height of BigFoot 5
y = height of Bigfoot 2
We must write an expression that relates both heights:
y = (1 / 4.9) * x
Then, replacing the height of BigFoot 5
y = (1 / 4.9) * (15.4) = 3.14cm
answer
the height of Bigfoot 2 is 3.14cm
