Hello!
1/4 is equal to 0.25. Let's divide below.
5/0.25=20
When dividing by fractions, you multiply by the reciprocal. The reciprocal of 1/4 is 4, and 5(4)=20
Therefore, our answer is 20.
I hope this helps!
A = (pi) * r^2
A = 3.14 * 11^2
A = 3.14 * 121
A = 379.94 miles
Using the law of sines, it is found that 1 triangle can be formed with the given conditions.
<h3>What is the law of sines?</h3>
Suppose we have a triangle in which:
- The length of the side opposite to angle A is a.
- The length of the side opposite to angle B is b.
- The length of the side opposite to angle C is c.
The lengths and the sine of the angles are related as follows:

Hence, for this problem, we have that the relation is:




G = 54º
A triangle can have one angle of 64º and another of 54º, hence 1 triangle can be formed with the given conditions.

Answer:
A1.) 87 + 63 =150
180 - 150 = 30
all the As is the same formula....
B1.) 180 - 123 = 57
57 + 82 = 139
180 - 131 = 41
