Question

in an isosceles triangle two angles are in the ratio 1 ratio 4 find the measure of angles of the triangle​

Answer 1

Answer:

there are two answers for this question

20,80,80 ; 30,30,120

Answer 2

Answer:

Let the angles be x and 4x.

In isoceles triangle, 2 angles have same magnitude.

$x + x + 4x = 180$

(Angle Sum property)

$= > 6x = 180$

$= > x = 180 \div 6$

$= > x = 30$

Therefore, 2 angles measure x = 30° and the other angle is 4x = 120°.

Similarly, if you take 4x as the 2 equal angles, you will get the 2 equal angles as 80° and the third angle as 40°.
