Answer:
The correct answer is 80, I do apologize if i'm wrong, haven't done that math in a few years
Step-by-step explanation:
One arc is shown as 110 deg.
The arc intersected by the 90-deg angle measure 90 deg.
110 + 90 = 200
360 - 200 = 160
That means the upper arc is 160 deg.
The angle made between a chord and a tangent is half the measure ofthe arc intersected by the chord.
b = 160/2 = 80
Answer: b = 80

Solve n by simplifying both sides of the equation, then isolating the variable.
n=7
10-7= 3 3+7=10 because if u subtract 10 by 7 gives u 3
Answer:
x = 15
y = 63
Step-by-step explanation:
9x - 7 + 4x - 8 = 180
13x = 195
x = 15
9x - 7 = 2y + 2
126 = 2y
y = 63
Simplify the expression
4n^3 - 12n^2 - 7n + 9
Hope this helps! :)
