Question

4. Two sides being given, calculate the third side marked by a letter in each right- angled triangle ​

Answer 1

Answer:

As we all know the formula is

H square = p square + b square

= (15) square + (8) square

= 225 + 64

H square = 289

H =√289

H = 17

Answer 2

Answer:

The image clearly shows a Right Angled Triangle. We have to find the Hypotenuse

Let,

a be 15 units

b be 8 units

c be Hypotenuse / b`

Pythagorean Theorem

a² + b² = c²

15² + 8² = c²

225 + 64 = c²

289 = c²

√289 = c

17 = c

So, the Hypotenuse / b` is of 17 units

Checking

15² + 8² = 17²

225 + 64 = 289

289 = 289

So, the answer is correct
