Answer:
x = 15°
Step-by-step explanation:
The secant- tangent angle x is half the difference of the intercepted arcs, that is
x =
(80 - 50)° = 0.5 × 30° = 15°
Mentally, they are numbers in which you can do mental math with since they are whole numbers
Are there answer choices or is this an essay?
<span>2n^2 - 7n - 3 = 0
a = 2
b = -7
c =-3
Then use the Quadratic formula:
x = [-b +-sqroot(b^2 -4*a*c)] / 2*a
