Answer:
x=2
Step-by-step explanation:
The angle formed by two tangents intersecting outside of a circle is half the difference of the intercepted arcs.
This implies that:

We need to simplify this ad solve for x to get:

Group the similar terms to get:

232=116x
Divide by 116 to get:
x=2
Answer:
AC = 55°
Step-by-step explanation:
In this geometry, arcs AC and BD have the same measure. The sum of the parts of arc CD will total the measure of CD.
AC + AB + BD = CD
2AC +80 = 170
AC = 110/2 = 55
The measure of arc AC is 55°.
Answer:
96 in²
Step-by-step explanation:
Lateral surface area
= 3 rectangles
(4×8) + (3×8) + (5×8)
32 + 24 + 40
96 in²
