Total angles of quadrilateral is 360°.
Add the given angles, 98° and 102°, and subtract the sum from 360°. Then, divide the difference by 2.
360° - (98° + 102)
= 360° - 200
= 160° the sum of the measure of the two other angles
160° ÷ 2 = 80°
ANSWER: The measure of the two other angles are 80° each.
--------
The measure of the angles of the quadrilateral which has no equal sides are 98°, 102°, 80°, and 80°
