Answer:
The new points to the triangle will be:
Step-by-step explanation:
Because the reflection point is at , all x values will subtract their distances from to get their new values. The y values remain the same.
The starting values are:
Point is 1 unit away from , so we'll subtract 1 from 2 to get the new x value: , so .
Point is also 1 unit away from , so we'll subtract 1 from 2 to get the new x value: , so .
Point is 3 units away from , so we'll subtract 3 from 2 to get the new x value: , so .
Area of triangle ABC can be found using the formula ¹/₂ × b × c × sin (A)
Substitute b = 9, c = 7, and m∠A = 66° into the formula gives
Area = 9 × 7 × sin 66° = 57.55
