Answer:
0.01667
Step-by-step explanation:
Make a drawing with a right triangle.
The opposite side, y, is the height of the dam less 1.65 m
The base or adjacent side is 90 m
The angle between the two sides is 90 m.
Then tan (26) = y / 90
y = 90 tan(26) = 90 (0.4877) = 43.90 m
The height of the dam is 43.90m + 1.65m = 45.55 m
So the trapezoid has 2 parallel sides making segments AD and BC transversals
Therefore making angle c and angle b add up to 180
(180-3x) + 3x + 180-9x +9x
180 +12x = 360
180= 12x
x= 15
The correct answer is C
Explain
The graph is given
F(x) is given -2^x
By putting x= - 3 in the first equation
G(x) = -9
Which is false
by putting x= -3 in the second equation
g(x) is also equal -9
Which is false
