<span>It is important to know that the sum of the three angles inside a triangle add up to 180 degrees. So then we get the following by adding up all three provided angle measures:
3x + (2x + 20) + (4x - 20) = 180
Some algebraic manipulation follows:
3x + 2x + 20 + 4x - 20 = 180
9x = 180
x = 180/9 = 20
The value of x is 20 degrees.</span>
Answer:
Step-by-step explanation:
Given: An ice chest contains 3 types of drinks: 10 apple juries 15 grape juices and 15 bottles of water.
Total drinks= 10+15+15 = 40 (Total outcomes)
Number of drink that does not contain fruit juice = Number of bottles of water = 15 (Favorable outcomes)
The probability of getting a drink that does not contain fruit juice =
So, the required probability = .
