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:

<h2>The answer is option B</h2>

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

<h3>6.50 to the nearest tenth</h3>

Hope this helps you

What is the equation of this line in slope-intercept form?
12345 [234]

Answer:

y = -2x + 5

Step-by-step explanation:

Slope-intercept form: y = mx + b

The slope of the line, m, is -2 because the line shows a negative trend and moves right 1 unit every time a point moves down 2 units.

The y-intercept, b, is 5 because the line crosses that number once on the y-axis.
