Answer:

x = 5

Step-by-step explanation:

Add all of the angles together. We know that the third one is 90° because it is a right triangle and the little square indicates a 90° angle.

7x + 16 + 39 + 90 = 180


Simply.


7x + 145 = 180

     -145    -145

7x = 35

/7      /7

x = 5

Solution:

<u>Note that:</u>

  • 7x + 16 + 39 + 90 = 180

<u>Simplify the equation:</u>

  • 7x + 16 + 39 + 90 = 180
  • => 7x + 145 = 180
  • => 7x = 35
  • => x = 35/7 = 5

HELP PLEASE THANK YOU! :) 50 POINTS !!!!!!!1
a_sh-v [17]

Answer:  0.88

Step-by-step explanation:  

Let C is the event of drinking coffee, T is the event of drinking tea and M is the event of drinking milk.

Thus, when we make the Venn diagram of the given situation according to the given information,

Total number of people = 50

Number of people who like coffee, tea and milk = 19

Number of people who like coffee, tea but not milk = 16

Number of people who like coffee, milk but not tea = 2

Number of people who like tea, milk but not coffee = 5

Thus, the number of people who like tea only = Total people - (people who like coffee, tea but not milk + people who like coffee, tea and milk + the one who only like tea and milk but not coffee)

= 50 - ( 16 + 19 + 5) = 50 - 46 = 4

Thus, Total number of the person who like milk = 16 + 19 + 5 + 4 = 44

⇒ Probability that this person likes tea = \frac{\text{ Total person who like to drink milk}}{\text{ Total number of people}} = \frac{44}{50} = 0.88

Find the distance between the two points in simplest radical form.<br> (7,2) and (-1, -3)
Paul [167]

Answer:

The answer is

<h2>\sqrt{89}  \:  \:  \:  \: units \\</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x_1 - x_2})^{2} +  ({y_1 - y_2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(7,2) and (-1, -3)

The distance between them is

d =  \sqrt{( {7 + 1})^{2}  +  ({2 + 3})^{2} }  \\  =  \sqrt{ {8}^{2}  +  {5}^{2} }  \\  =  \sqrt{64 + 25}  \\  =  \sqrt{89}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

\sqrt{89}  \:  \:  \:  \: units \\

Hope this helps you
