What are the values of perpendicular and legs in the following triangle?  posted Oct 6, 2016

+1 vote

Let A = value of perpendicular
Let B = value of leg facing side 9
Let C = value of leg facing side 16
We can write the following equations
9^2 + A^2 = B^2
16^2 + A^2 = C^2
B^2 + C^2 = 25^2
Then,
2A^2 + 9^2 + 16^2 = 25^2 , A = 12
9^2 + 12^2 = B^2 , B = 15
16^2 + 12^2 = C^2 C = 20 answer Oct 19, 2016 by anonymous answer Oct 7, 2016

Guess work confirmed by the Pythagorean Theorem would be - going from left to right:
15, 12. 20. answer Oct 8, 2016

Find the Area of the Right Angled Triangle whose hypotenuse is 11 cm and perpendicular from the right angle vertex on the hypotenuse is 6 cm.

In the figure, semicircles are constructed on the hypotenuse and legs of a right angle triangle. If S1, S2 are the area of shaded regions and S is the area of right angled triangle, which of the following is true and why ?

1. S1 + S2 = S
2. S1 + S2 = 2S
3. S1 + S2 = 3S +1 vote
