Answer:
27.2 mm²
Step-by-step explanation:
Area of the triangle = ½*base*height
base = 8 mm
height = 6.8 mm
Area = ½*8*6.8
= 4*6.8
= 27.2 mm²
or
divide both sides by 2
sinΘ = -
Since the sin ratio is negative then Θ is in third / fourth quadrants
Θ = () = related acute angle
Θ = ( π + ) =
or Θ = ( 2π - ) =
