Answer:
108
Step-by-step explanation:
65+110+87=252
360(Total angle of quadrilaterals)-252=108
That it has the highest y-intercept of all of the three linear functions.
(and that the question could be worded better, but don't put that in your answer)
Step-by-step explanation:
cot x / (1 + csc x)
Multiply by conjugate:
cot x / (1 + csc x) × (1 − csc x) / (1 − csc x)
Distribute the denominator:
cot x (1 − csc x) / (1 − csc²x)
Use Pythagorean identity:
cot x (1 − csc x) / (-cot²x)
Divide:
(csc x − 1) / cot x
