I can’t solve it without the diagram (or the missing angle/altitude information). Could you upload the picture or tell me the angle measures or which side is the base?
Meanwhile, here are the formulas you’ll need once you give the missing value (assume the base = 11 and the two equal sides = x):
- If the vertex angle (angle between the two equal sides) is θ:
x = 11 / (2 sin(θ/2))
- If you know the altitude (height) from the vertex to the base, h:
x = sqrt(h^2 + (11/2)^2)
- If the triangle is an isosceles right triangle with hypotenuse 11 (a common case):
x = 11 / sqrt(2) ≈ 7.8
Tell me the diagram or the relevant angle/height and I’ll compute x to the nearest tenth.
