AB
It is indicated in the figure and is valid:
m AB = 49
m ABC
Angle resulting from the following subtraction:
m ABC = 360-107 = 253
m BAC
Angle resulting from the sum of the two angles shown in the figure:
m BAC = 107 + 49 = 156
m ACB
Angle resulting from the following subtraction:
m ACB = 360-49 = 311
It is b I think if it’s wrong sorry
X is 135 degrees
Hope it helps.
The area of ANYTHING circular is (pi) x (the circle's radius)².
Radius = 1/2 of the diameter
Radius of the mirror = 6 inches
Area of the mirror = (pi) x (6 inches)²
= (pi) x (36 inches²) = <em>113 square inches</em> (rounded)
