Question

One of the two equal angles of an Isosceles triangle measures 45 degrees. Find the third angle.​

Answer 1

Answer:

the sum of thhe triangle is 180 degree. so in sosceles triangle two angles are equal.whiach is 45+45=90.so third angle is 180-90=90degree. Ans is 90degree

Step-by-step explanation:

Answer 2

✩$\rm\bf\underline{Solution:}$

As we know that

in an isosceles triangle two angles are equal

and here that two angles are of 45°

and let the third angle be x

Now,

the sum of all angles of triangle is 180°

So,

➪ 45° + 45° + x = 180°

➪ 90° + x = 180°

➪ x = 180° - 90°

➪ x = 90°

✪ by this way the third angle of the ssls triangle is 90°
