Question

In an isosceles triangle if one base angle is 55°. Find the other two angles
angles is
​

Answer 1

Answer:

the angles are 62.5 and 62.5

Step-by-step explanation:

let the vertex angles be 2X

2x+55=180

2x=180-55=125

x=125/2=62.5

Answer 2

Step-by-step explanation:

in an isosceles triangle , 2 opppsite sides are equal so sides opposide to equal sides are also equal so now we have 2 angles = 55°

let the third angle be X

now by the angle sum property of a triangle

55° + 55° + x = 180°

110° + x = 180°

x= 180 - 110

x= 70°

Therefore ,the 3 sides are 55° , 55° and 70°
