if an exterior angle of a triangle is 130 degrees and one of the interior opposite angle is 60? find the other interior opposite angle

Open in App

Solution

Dear Student

we know,

an exterior angle of a triangle = sum of the two opposite interior angles

let the second interior angle be x

Then,

130 = 60 + x

x = 130 - 60

x = 70 is the other interior angle

and

third angle of the triangle = 180 - (70 + 60)

= 180 - 130

= 50
