Answer:
the angle are 50, 47, 83
Step-by-step explanation:
we know that the sum of the three angles of the triangle is 180 degree
now, 4x+22+3x+26+9x+20=180
x=7
the angle are 50, 47, 83
Answer: 0.5
Step-by-step explanation:
A dice has numbers 1, 2, 3, 4, 5 and 6. This means there are 6 outcomes that a person can get once it's rolled.
Since the numbers are from 1-6, the even numbers are 2, 4 and 6. This implies that there are 3 even numbers out of possible 6 numbers.
Therefore, the theoretical probabiltity of rolling an even number on a dice will be:
= Number of even numbers / Total numbers
= 3/6.
= 1/2
= 0.5
