9514 1404 393
Answer:
x = 30
Step-by-step explanation:
In an arithmetic sequence, any given term is the average of the two terms that come before and after. The middle term of this sequence must be ...
2sin(3x) = (-11 +15)/2
sin(3x) = 1 . . . . . . . . . . simplify and divide by 2
Then the value of 3x must be 90°, so ...
x = 90/3 = 30
There is one value of x in the interval [0, 90] that makes this sequence arithmetic: x = 30.

A comedian needs up to ten volunteers: x+y ≤10.
y≥0
Answer:
50 degrees
Step-by-step explanation:
x + y = 90
x = 2y - 30
2y - 30 + y = 90
3y - 30 = 90
3y = 90 + 30
3y = 120
y = 120/3
y = 40
x = 2y - 30
x = 2(40) - 30
x = 80 - 30
x = 50 <====== angle x
