Question

if one angle is a isosceles triangle is 70 degree find the other two angle​

Answer 1

sum of the angles => 180°

180= 70+ 2x

2x= 180-70

2x= 110

x= 110/2

x= 55°

each of the two angles is 55°

Answer 2

we know that two sides of isosceles triangle are equal so the two angles be x

sum of all angle =|80

70+x+x=|80

2x = ||0

x=55

so the other two angles are 55°
