Answer:
the total of angle's in traingle is 180
so 85+53+c=180
c=180-138
c=42
Answer:
tan A = -15/8.
Step-by-step explanation:
sin^2a = 1 - cos^2A
= 1 - (-8/17)^2
= 225/289
So sin A= 15/17
tan A = sin A / cos A
= 15/17 / -8/17
= 15/-8
= -15/8.
Step-by-step explanation:
We can set up an average equation in the form, where x is the last score in the fourth quarter:


She needs at least a 95 on the last quarter to average 90 in all four quarters.
