Area of triangle = 1/2 ABsinC
Since all sides are equal, it means it is an equilateral triangle
⇒All angles are 60°
Area of triangle = 1/2 ABsinC
Area of triangle = 1/2 (3.5)(3.5)sin(60°)
Area of triangle = 5.3 in²
Answer:
k=4
Step-by-step explanation:
C = sqrt(e/m)
You can get this by first dividing away the m and then taking the square root of both sides.
