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:

$55=\frac{1}{2}(116x+3-(180-55))$

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

$110=(116x+3-125)$

Group the similar terms to get:

$110-3+125=116x$

232=116x

Divide by 116 to get:

x=2

What’s the area of the sector

Stella [2.4K]

Answer:

Step-by-step explanation:

If the sector wasn't there, the area would be that of a circle. The formula for a circle = pi * r^2

But the sector is there and so you have to account for it.

Area sector = (60/360) * pi * 11^2

Area sector = 1/6 * pi * 121

1/6 of 121 = 20.17

Area of sector = 20.17 pi square cm
