Question

In a triangle an exterior angle vertex is 95° and it's one of the interior opposite angles is 55°. find all the angles of the tringles​

Answer 1

Answer:

all angles of triangle are = 55 , 40, 85

Step-by-step explanation:

interior angles = 55 degree and x degree

exterior angle = 95 degree

exterior angle = sum of opposite interior angle

95 = 55 +x

95-55 = x

x = 40 degree

let third angle be y

y +55+40 = 180

y+95 = 180

y = 180-95

y = 85 degree
