Question

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

Answers:
A: 4.2
B: 6.5
C: 12.1
D: 8.8

Answer 1

B

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

The answer is option B

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 = √(54.76 - 12.96) \\ x= √(41.8) \\ x = 6.465291950...`

We have the final answer as

6.50 to the nearest tenth

Hope this helps you
