Answer:
The area of the triangle is
Step-by-step explanation:
Given:
Coordinates D (0, 0), E (1, 1)
Angle ∠DEF = 60°
△DEF is a Right triangle
To Find:
The area of the triangle
Solution:
The area of the triangle is =
Here the base is Distance between D and E
calculation the distance using the distance formula, we get
DE =
DE =
DE =
DE =
Base =
Height is DF
DF =
DF =
DF =
Now, the area of the triangle is
=
=
=
=
-3 + -3 = 0
-5 + 1 = -4
vector = < 0,-4 >
