Answer:
d: 15 units squared
Step-by-step explanation:
The area of a triangle is :
- Base: 5
- Height: 6
- Area: (5•6)/2=30/2=15
Point M of the triangle is (-2,2) to make triangle MNP as shown in the attached image
Triangle MNP has a base of 4 units and a height of 4 units. We can work out the angle x and angle y using trigonometry ratio
We use tan ratio to find both angles
Angle MNP = Angle NMP = 63.43 degrees (this is based on the fact that the triangle is an isosceles triangle)
Angle MPN = 2×26.6 = 53.2 degrees (we multiply by 2 as angle y is only a half of angle MPN - as shown in the diagram)
