Answer:
Step-by-step explanation:
Given
Two sides of triangle of sides 5 ft and 7 ft
and angle between them is increasing at a rate of 0.9 radians per second
let 
is the angle between them thus
Area of triangle when two sides and angle between them is given
Differentiate w.r.t time

The answer for this question is 0.2
The root of 77 is 8.774 so the answer is C
Answer: C
F(x)=2x+1
you can use a table of values for a diagram and graph the line
M> 1 + m>2 = 90°
x-12 + 5x = 90°
6x - 12 = 90°
6x -12 +12 = 90°+12
6x = 102
6x/6 = 102/6
x = 17
m>1 = x-12
m>1 = 17-12
m>1 = 5
m>2 = 5x
m>2 = 5(17)
m>2 = 85
