Question

If the exterior angle of a triangle measures 130° and of the interior opposite angles is 80°, then the measure of the
other interior opposite angle is

Answer 1

Step-by-step explanation:

we khow

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

let the second interior angle be x

then ,

130 = 80 + x

x = 130 - 80

x = 50

now

third angle of the triangle = 180 - (50 + 80 )

= 180 - 130

= 50
