Question

4. An exterior angle of a triangle is 130° and one of the interior opposite angles is 45. Find
the other two angles of the triangle​

Answer 1

Step-by-step explanation:

• Let A,B and C is a triangle.
• on outside of c is 130°.
• So, angle is c = 180 -130 = 50°.
• we know that, the sum of two interior angle is equal to exterior angle.
• Sum of triangle = 180°.
• 45°+50°+b = 180°.
• So, b = 180 - 95°= 85°.
• Hence the two angles are 50 and 85.
