Answer:
the group bought 10 burger and 12 drinks
Step-by-step explanation:
6.25×10=62.5
92.50-62.5=30
30÷2.50=12
Step-by-step explanation:
the given data is
tanθ = 2.773 and 0<θ<π/2
this implies θ = tan inverse(2.773)
⇒ θ = 70.16°
Therefore, sinθ = sin70.16° = 0.9406
similarly,cosθ = cos70.16° = 0.3393
therefore, values of sinθ and cosθ are 0.9406 and 0.3393 respectively.
