Step-by-step explanation:
1.
Therefore,
2.
Use the identity
We chose the negative value of the cosine because of the condition where cot y > 0. Otherwise, choosing the positive root will yield a negative cotangent value. Now that we know the sine and cosine of y, we can now solve for the tangent:
3. Recall that sec x = 1/cos x, therefore cos x = 5/6. Solving for sin x,
Solving for tan x:
Answer:
80
Step-by-step explanation:
28-28=0
0-12= -12
28+12 = 40
28-40 = -12
40 is the increase
40 is half of 80
So, the answer is 80
To check: -12 + 40 (half of a number; 80) = 28
