1.	21. An exterior angle of a triangle is of measure 130' and one of its interior opposite angles is of measure 60'. Find the measure of the otherinterior opposite angle.?? To sunnlementary anales are in the ratio 7. ? find the other interior opposite angle.
Answer» EXTERIOR Angle = Sum of INTERIOR opposite angles ( In a Triangle ) To Find Measure of other interior angle Given Exterior Angle = 130° One of the Interior Angle = 60° ASSUMPTION Let another interior angle be x. SOLVING Using Concept 130° = 60° + x x = 70° ANSWER So, the another interior angle is 70°.
