Question

Two of the altitudes of a triangle are 10cm and 11cm. which of the following cannot be the length of the third altitude
a 4 b 5 c10 d 7
and tell me how i mean the way pLZ·········

Answer 1

It's a difficult one.
See anywhere else.

Answer 2

Answer:

option q and option b cannot be the third altitude

Step-by-step explanation:

h1h2/h1+h2 < h3 < h1h2/h2-h1      ------->(1)

10*11/10+11 < h3 < 10*11/11-10

110/21 < h3 < 110/1

5.6 < h3 < 110

hence 4,5 cannot be third altitude.

I think the options what you mentioned below the question was wrong its (a)5 and (b)6.once check it.

equation (1) can be derived using basic property of triangle i.e. |c-a| < b < |c+a| and side is inversely proportional to altitude.
