Question

if the unequal angle of an isosceles triangle is90,find the other angles

Answer 1

the unequal of an isosceles triangle is 90(given)
let the equal angles of a triangle be "x" and "x"
therefore according to angle sum property of a triangle,
90+x+x=180
90+2x=180
2x=180-90
2x=90
x=90/2
x=45
the angles are 90,45,45

Answer 2

All triangle are of 180.
In an isosceles triangle two angle are same and one is different.
Therefore, if an unequal angle is 90 then,
equation,
2x+90=180
2x=180-90
2x=90
x=90÷2
x=45
Therefore, the two equal angles are 45.
