a = 21
b = 21
Solution:
Figure (1): The given triangle is a right angle triangle.
One leg of the triangle (b) = 20
Hypotenuse of the triangle (c) = 29
Another leg of the triangle = a
Using Pythagoras theorem, find a:
Taking square root on both sides, we get
⇒ a = 21
Hence a = 21 is the correct answer.
Figure (2): The given triangle is a right angle triangle.
One leg of the triangle (a) = 72
Hypotenuse of the triangle (c) = 75
Another leg of the triangle = b
Using Pythagoras theorem, find b:
Taking square root on both sides, we get
⇒ b = 21
Hence b = 21 is the correct answer.
