Answer:12.1

Step-by-step explanation:

Angle D=180-(82+52)

Angle D=180-134

Angle D=46

Using sine rule

e/sinE=d/sinD

e/sin52=11/sin46

e/0.7880=11/0.7193

e/0.7880=15.29

Cross multiply

e=15.29 x 0.7880

e=12.05

e=12.1 approximately

What percentage of the people liked Rocky the most ?
Ede4ka [16]

Answer:

15%

Step-by-step explanation:

The amount of people who likes Titanic is 25%, because there are 360° in a circle and 90° is used for Titanic. Hence

\frac{90}{360}  =  \frac{25}{100}

To find the percentage of people who liked Rocky the most, we subtract the rest from the total (100%)

100 - 25 - 20 - 30 - 10 = 15

Therefore, 15% of the people liked Rocky the most.

What is the distance between (1, -4) and (1, 18​
Annette [7]
<h3>Answer: 22 units</h3>

=====================================================

Explanation:

You can use the distance formula

d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{ (1-1)^2 + (-4-18)^2}\\\\d = \sqrt{ (0)^2 + (-22)^2}\\\\d = \sqrt{ 22^2}\\\\d = 22\\\\

----------------

A shorter method is to subtract the y coordinates and apply absolute value

So either |-4-18| = |-22| = 22

Or, |18 - (-4)| = |18+4| = |22| = 22

This method only works because the x coordinates are the same. We can also use this method if the y coordinates were the same with the x coordinates being different.
