Step-by-step explanation:
Alright, archtan /
tan
−
1
(
x
)
is the inverse of tangent. Tan is
sin
cos
. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.
Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.
Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.
Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.
Answer: 24 cm^2
explanation: the area of the triangle would be 6 because (3*4)/2=6. the area of the larger rectangle would be 12 because 4*3=12. the missing side is found by subtracting 8 by 4. the smaller rectangle’s area would be 6 because 4*1.5=6. add 6, 12, and 6 together and you get 24. i hope this helps!!
