Find the missing angle of a triangle with 60 degrees and 40 degrees

1 answer:

3 0

The sum of the interior angles of a triangle = 180 degrees. So, all of the angles on the inside of the triangle will add up to 180.

60 + 40 + ? = 180

100 + ? = 180

? = 80

The missing angle in the triangle is 80 degrees.

Hope this helps!

t is commonly assumed that babies are equally likely to come as either a boy or a girl. This is not true. Actually, about 51.3%

Answer:

The probability they have one boy and one girl = 0.50 = 50 %

Step-by-step explanation:

Here the family has two children, we need to find what is the probability they have one boy and one girl.

Probability for babies are boys = 51.3% = 0.513

Probability for babies are girls = 1 - 0.513 = 0.487

The probability they have one boy and one girl = 1 - probability that they have two boys - probability that they have two girls

The probability they have one boy and one girl = 1 - 0.513² - 0.487² = 0.499 = 0.50

The probability they have one boy and one girl = 0.50 = 50%
