Question

Please help I don’t understand what to do

Answer 1

x⁰ = 360 degree- ( 246⁰ + 66⁰)

= 360 degree- 312⁰

= 48 ⁰

Answer 2

x = 114

Explanation:

Remark

You are trying to figure out what the arc is in degrees. The arc formula is

Intersect angle = 1/2( the furthest arc - the smaller closer arc).

Givens

Intersect angle = 66 degrees

Closer arc = x

Further or largest Arc = 246

Solution

66 = 1/2 (246 - x) Multiply both sides by 2 and remove the brackets.

132 = 246 - x Subtract 246 from both sides.

132 - 246 = - x

- 114 = - x Multiply both sides by -1

-1 (-114) = -1 * (-x)

x = 114
