Question

find the unknown angles (X/y) in each figure​

Answer 1

Answer:

x=70

Step-by-step explanation:

x+x+40= 180 (angle sum property of a triangle)

2x=180-40=140

x=140/2=70

Answer 2

Answer:

Opposite sides are equal, so it's an isosceles triangle

Hence , two of its angles are equal

sum of all angles in a triangle= 180°

40+X+X= 180

2x= 140

X= 70°

so, 70°,70° and 40° are the angles of triangle
