ANSWER:
Point in original figure (2, -3)
Point in final figure (-3, -2)
STEP-BY-STEP EXPLANATION:
The first thing is to determine the original point of the figure on the graph, which would be:
The rule for 270° counterclockwise rotation is as follows:
We apply it in this case, and the new point would be:
We represent the result on the graph, as follows
Answer:
One solution.
Step-by-step explanation:
To determine the number of possible solutions for a triangle with A = 113° , a = 15, and b = 8, we're going to use the law of sines which states that: "<em>When we divide side a by the sine of angle A it is equal to side b divided by the sine of angle B, and also equal to side c divided by the sine of angle C</em>".
Using the law of sines we have:
Solving for B, we have:
∠B = 29.4°
Therefore, the measure of the third angle is: ∠C = 37.6°
There is another angle whose sine is 0.4909 which is 180° - 29.4° = 150.6 degrees. Given that the sum of all three angles of any triangle must be equal to 180 deg, we can't have a triangle with angle B=113° and C=150.6°, because B+C>180.
Therefore, there is one triangle that satisfies the conditions.
