Since you know that the angles in a triangle add up to 180°, you can solve for x by making it an equation:
2x + x + 14 + x - 38 = 180
4x - 24 = 180
+ 24
4x = 204
÷ 4
x = 51
Now you can substitute x in to the angles
51 × 2 = 102°
51 + 14 = 65°
51 - 38 = 13°
I hope this helps!

First you would need to solve x.
2x+x+14+x-38=180
4x-24=180
4x=204
x=51
Now plug in the x for all three angle measures.
2(51)=102 degrees
51+14=65 degrees
51-38=13 degrees
Final answer is 102 degrees, 65 degrees, 13 degrees

If a tellemarketer made 200 phone calls and 35 customers signed up what is the relative frequency of getting a customer and not

Snezhnost [94]

Answer:

82.5% and 17.5%

Step-by-step explanation:

The telemarketer made 200 phone calls and only 35 people signed up. Therefore, we need to find the amount of people who didnt.

200 - 35 = 165

165 people did not sign up.

This meants that the frequency of getting a customer is 35/200 and not is 165/200. In percentages,

The relative frequency of not getting a customer is 82.5%

The relative frequency of getting a customer is 17.5%
