Find the value of x in the triangle in the picture.

Answer:

x = 33

Step-by-step explanation:

since the sum of interior angles of a triangle is 180 so simply add the given angles and make it equal to 180 degrees

x + 114 + 33 = 180

x + 147 = 180

x = 180 - 147

x = 33

to check whether the above value of x is correct simply just put the above value of x in

x + 114 + 33 = 180

33 + 114 + 33 = 180

180 = 180

since both sides are equal so that means the above value of x is correct

Answer:

X equals 33 degrees

Step-by-step explanation:

Every triangle equals a total of 180 degrees. If you add 114 and 33 you get 147 degrees. You subtract 147 from 180 to get your answer for X, Which is 33 degrees.

Help plsss it’s timed i need to passss plsss

Answer:

65°

Step-by-step explanation:

To obtain Angle A, we use the cosine rule ;

Cos A = (b² + c² - a²) / 2bc

Cos A = (12² + 14² - 14²) / 2(12)(14)

Cos A = 144 / 336

A = Cos^-1(144/336)

A = 64.62°

A = 65°

A cleaning company charges a fee of &65 in addition to $10.50 per hour of cleaning, let x represent the number of hours clea
photoshop1234 [79]
Fee of $65
$10.50 per hour

'x' represents hours

Therefore we have:

y = 10.50x + 65

Because 10.50 is the cost per hour, and x represents hours, so we put these together. 65 is a one-time fee, so we just add it on.

30 points.. Please Help! I don't understand what to do with this question...a bit confused.
Romashka-Z-Leto [24]
  Eh, here's my best try for a table:

                       <u>Like tv</u>          <u> don't like tv</u>       <u>total</u>
<u>Like reading:</u>     70                     10                 80
 <u>Don't like read</u>. <u>20</u>                     <u>30</u>               <u>50 </u> 
      <u>total </u>              90                    40               130

The percentage of students that like tv as well as reading is- 70 divided by 130 which gives you .538 which in percentage is 53.8%.

The probability of a student that does not prefer to watch tv as also does not like to spend their time reading is 30 over 40 which can be simplified or reduced to 3 over 4. [30/40 reduced to 3/4]

Hope this somehow helped you :)
