Question

What is the value of the missing side? Round answer to the nearest tenth.

Answer 1

Answer:

B

Step-by-step explanation:

a² + b² = c²

a = 3.6

c = 7.4

3.6² + b² = 7.4²

12.96 + b² = 54.76

b² = 41.8

b ≈ 6.5

Best of Luck!

Answer 2

Answer:

The answer is option B

Step-by-step explanation:

Let the missing side be x

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

a² = b² + c²

where

a is the hypotenuse

From the question

a = 7.4

So we have

${7.4}^{2} = {x}^{2} - {3.6}^{2} \\ {x}^{2} = {7.4}^{2} - {3.4}^{2} \\ x = \sqrt{54.76 - 12.96} \\ x= \sqrt{41.8} \\ x = 6.465291950...$

We have the final answer as

6.50 to the nearest tenth

Hope this helps you
