Answer:

Step-by-step explanation:
Here, we have the known angle sandwiched between two known sides.
So, we have SAS.
And we want to find the side opposite to the angle.
Therefore, we can use the Law of Cosines:

Again, it is important what we substitute.
a and b are the two side lengths. So, we will substitute 8 for a and 13 for b.
C is our angle. So, substitute 64 for C.
And c is what we’re trying to solve.
Therefore:

Simplify:

Add:

Take the square root of both sides:

Use a calculator. So, c is approximately:

The c is our y. So, y is approximately 11.9 units.
Answer:

Answer:
0.87
Step-by-step explanation:
Out of a total number of 100 questions, Daniel is said to have answered 87.
We first express this as a fraction.
Total number of questions he answered divided by total number of quiz questions
= 87/100
As a decimal, 87 divided by 100 = 0.87.
You can easily get this by using the calculator.
