Find the length of the missing side in the figure below. a = _______ cm.

WITCHER [35]

Answer:

$\frac{2 \sqrt{177} }{5}$

5.32cm correct to 2 decimal places

Step-by-step explanation:

This is a right angled triangle from what I know so we have to apply pythagoras theorem.

${7.1}^{2} = {a}^{2} + {4.7}^{2}$

we need to rearrange this to find a²

${a}^{2} = {7.1}^{2} - {4.7}^{2}$

$a = \sqrt{ \frac{708}{25} }$

This can either be written as a fraction or decimal.

$a = \frac{2 \sqrt{177} }{5}$

$a = 5.32$

correct to 2 decimal places

2/3 divided by 5 is it 2/3 times 1/5=2/15

drek231 [11]

(2/3)/5

Yes. (2/3)/5 is the same as 2/15 because:

(2/3) = (0.67)/5 = 0.133 (continuing)

(2/15) = 0.133 (countinuing)

What is midpoint of A(2, 3) and B(-2, 5)?

Elis [28]

Answer:

The midpoint of A and B is (0, 4).

Step-by-step explanation:

Use the midpoint formula, ((x₁ + x₂)/2 , (y₁ + y₂)/2)

First, solve for the x part.

(2 + (-2))/2

0/2

So the x-coordinate of the midpoint is 0.

Then, solve for the y part.

(3 + 5)/2

8/2

So the y-coordinate of the midpoint is 4.
