what is the measure of angle x in the picture below?
answers can be either: (in case pic is to unreadable)
a. 45°
b. 80°
c. 55°
d. 100°

B. 80

Step-by-step explanation:

Angle X and Y are vertically opposite angles so:

180° - 45° - 55° = Y°

80°= Y° = X°

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
