a) Name the highlighted arc and determine if it is a major arc, minor arc, or semicircle.
b) Find the measure of the highlighted arc.

4.067units.

Step-by-step explanation:

(a) The highlighted arc is the major arc. That is , it covers from G to I.

(b) The length of the major arc will be

πr0°/180 where the angle substended at the center by the highlighted arc is

360° - 127° ( the angles if the arc not highlighted)

= 233°

Though this radius of the circle was not given so we are going to find the arc length without necessarily defining the radius.

Arc length = π × r × 233°

180

= 3.142 × r × 233°

180

= 4.067runits.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
