Question

In the given figure (not drawn to scale), OABC is a quadrilateral with ABC on horizontal ground and O is vertically above A. M is the mid-point of BC. If ∠BAC = 90°, AB = AC = 16 cm and OA = 12 cm, calculate the length of OB.



​

Answer 1

Is the figure 3d?

If not then the question's wrong.

In triangle ABO, Angle OAB=180 degrees( Not possible).

So the triangle's also not possible.

Check the question once again.

Or another solution can be that we say that OAB is a straight line since angle OAB = 180 degrees.

Therefore OB= 16 cm+12cm =28 cm.

Hope it helps you ^_^ Like if you think its right.
