To find each of the angles we must make the following clearances:
For ∠A
sin A = 0.96
A = Asin (0.96)
A = 73.7 degrees
For ∠B
tan B = 0.53
B = Atan (0.53)
B = 27.9 degrees
For ∠C
cos C = 0.44
C = Acos (0.44)
C = 63.9 degrees
Answer:
approximate measures of ∠A, ∠B, and ∠C are:
A = 73.7 degrees
B = 27.9 degrees
C = 63.9 degrees

Answer:
f^-1 (x) = 1/2x -5/2
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y = 2x+5
Exchange x and y
x = 2y+5
Solve for y
Subtract 5 from each
x-5 = 2y+5-5
x-5 = 2y
Divide by 2
(x-5)/2 = 2y/2
1/2x - 5/2 = y
f^-1 (x) = 1/2x -5/2
x and the blue 100 are vertical angles, which mean they are the same.
x = 100
