Question

An exterior angle of a triangle is 130° . If one of the interior opposite angles is 65° , find the other two angles of a triangle.

Answer 1

Step-by-step explanation:

we know,

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

Now,

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

= 180 - 130

= 50

Answer 2

Step-by-step explanation:

let the second interior angle be x

Then,

130 = 60 + x

x = 130 - 60

x = 70

Now,

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

= 180 - 130

= 50
