In an isosceles triangle, one angle is four times the other angle. Find the corners of this triangle.

In an isosceles triangle, 2 angles are equal.
Let x be the first corner of the triangle and x the second corner of the triangle.
Since, in an isosceles triangle, one angle is 4 times larger than the other, it means:
4 * x is the third corner of the triangle.
Let’s make an equation.
x + x + 4 * x = 180, since the sum of all the angles of the triangle is 180.
x * (1 + 1 + 4) = 180;
x * 6 = 180;
x = 180/6;
x = 30;
Find the value of the expression: 4 * x = 4 * 30 = 120.
From this we get that 2 angles are equal to 30 °, and the third angle is 120 °.
Answer: 30 °; 30 °; 120 °.
