Question

If base and perpendicular of right angled

triangle are 7cm and 8cm than hypotenuse

will be

a)15cmb) 113cm
c)√113 cm d)√13 cm​

Answer 1

Answer:

56.5 cm

Step-by-step explanation:

Let the third side(hypotenuse) be x

Using Pythagoras theorem,

(7)²+(8)²=x²

49+64=x²

113=x²

56.5=x

Therefore the length of the third side is 56.5 cm.

Answer 2

Before, finding the answer. Let's find out we can find the answer.

• In this question, we have to find the Hypotenuse.
• So, to find the Hypotenuse, we must use the Pythagoras theorem which is :

$\boxed{ \tt Pythagoras \: theorem= \sqrt{a^2 + b^2} }$

• Here, we have to multiply the base with the base and perpendicular with the perpendicular. Then, we must find the square root of the product.

Given :

• Side 1 = 7 cm
• Side 2 = 8 cm

To find :

• hypotenuse

Solution :

We know that,

${ \tt Pythagoras \: theorem= \sqrt{a^2 + b^2} }$

                                 $\tt = \sqrt{7^2 + 8^2} }$

Now,

Value of 7 × 7 = 49

Value of 8 × 8 = 64

                                 $\tt = \sqrt{ 49 + 64} }$

                                 $\tt = \sqrt{ 113 }$

Therefore, option (c) is the right answer.
