The answer would be C. ADB:310 degrees.

A major arc includes 3 points. So that eliminates answer choices B and D.

Angle ACB is a central angle and intercepts the arc AB. The measure of the central angle and the arc it intersects have the same measure. Meaning that Arc AB equals to 50 degrees.

A circle is equal to 360 degrees. So subtract the measure of the minor arc to 360 to get the measure of the major arc.

360-50=310.

Making arc ADB equal 310 degrees

Find the measure of angle 3<br> I WILL GIVE BRAINLIEST TO THE CORRECT ANSWER
Mice21 [21]

Answer:

82°

Step-by-step explanation:

i. 8x +26 = angle 5 (corresponding angles)

ii. angle 5 = -9x + 179 ( vertically opposite angles)

so,

8x+26= -9x +179 (from i and ii)

or, 17x= 153

therefore, x= 9

now,

angle3 + 8x +26= 180° (linear pair)

angle 3 = 180°- 72-26

hence, angle 3= 82°
