Question

if one angle of an isosceles triangle is 70 and the other two are equal , find the angles​

Answer 1

One angle of isosceles triangle is 70o. We know that, in an isosceles triangle 2 angles are equal corresponding with 2 equal sides, If 70o is 3rd angle of triangle, 70o + x + x = 180o 2x + 70o = 180o 2x = 180o – 70o x = (110o/2) x = 55o So, both angles are 55o Consider the 70o as base angle of isosceles triangle Then, 70o + 70o + x = 180o x = 180o – 140o x = 40o So, one angle is 40o and another is 70oRead more on Sarthaks.com - https://www.sarthaks.com/792124/isosceles-triangle-angle-70-the-other-two-angles-are-55-and-55-70-and-40-iii-any-measure

Answer 2

Answer:

55° because a ( angle sum property of a triangle is 180°) so 70-180=110 now we have to divide 110 in two parts 110÷2=55°
