Answer:
see the attachments
Step-by-step explanation:
Actually, the given description fits 3 different triangles. They differ in the size of the included angle, hence the length of the remaining side. Possibilities are ...
- included angle: 91.5°; third side: 20.9
- included angle: 59.5°; third side: 14.6
- included angle: 20.5°; third side: 6.0
_____
When the non-included angle is opposite the long side, there is only one solution to the triangle. (See the first attachment.)
When the non-included angle is opposite the shorter of the given sides, there are generally two possible solutions. One of these has an acute angle opposite the long side; the other has an obtuse angle opposite the long side.
In any event, the Law of Sines is used to solve the triangle. First, the angle opposite the other given side is found; then the remaining angle and the side opposite it.
Suppose the given sides are "a" and "b", and the given angle is A. Then the Law of Sines tells you ...
B = arcsin(sin(A)·b/a) . . . . . possibly 2 values
From which ...
C = 180° -A -B
which allows finding ...
c = a·sin(C)/sin(A)
Easy!
Wouldn’t it just be

Answer:
The correct answer is -3
Step-by-step explanation:
attached is a number line to show diagrammatically how to count five units from the chosen point to point 2 on a number line.
Moving five units from -3 to 2 on a number line is given as follows:
-3 ⇒ -2 ⇒ -1 ⇒ 0 ⇒ 1 ⇒ 2
From the motion expression shown above, moving from -3 to 2 involves moving 5 units.
another way of determining the correct answer is to find the difference in interval between the two points as shown below:
Let the point be x
2 - x = 5 units
2 - 5 = x
∴ x = -3
8,000 is 10 times as much as 800
