Answer:

Step-by-step explanation:

Solution :

Remember that the sum of complementary angles is always 90°.

First, finding the value of x :

Set up an equation :

( Being complementary angles )

Solve for x

{ Remove unnecessary parentheses }

{ Combine like terms }

{ Subtract 3 from 30 }

{ Move 27 to right hand side and change it's sign }

{ Subtract 27 from 90}

{ Divide both sides by 9 }

The value of X is 7°

Now, Replacing the value of x in order to find the value of  B

{ Plug the value of x }

{ Multiply 7 by 7 }

{ Subtract 3 from 49 }

The measure of  B is 46°

Mi is about to roll a six-sided number cube. What is the experimental probability that she will roll an even number based on her
Kryger [21]

Answer: The  experimental probability that she will roll an even number= \frac{1}{2}


Step-by-step explanation:

We know that the probability for any event is given by6;-

\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}

In a dice, the total even numbers (2,4,6)= 3

Therefore, the probability that she will roll an even number will be given by:-

\text{Probability}=\frac{\text{3}}{\text{6}}=\frac{1}{2}

Hence, The  experimental probability that she will roll an even number= \frac{1}{2}
