Answer:
cos y° = b divided by 6
Step-by-step explanation:
Trigonometric ratios :
We are given that sin y° = a divided by 6
On comparing
Perpendicular = a
Hypotenuse = 6
tan y°=a divided by b
On comparing
Perpendicular = a
Base = b
So,
So, Option d is true
cos y° = b divided by 6
Answer:
Option (3)
Step-by-step explanation:
The ramp shown in the figure is in the shape of a triangular prism.
Therefore, total surface area of this ramp = Area of the triangular sides + Area of the base + Area of the vertical side + Area of the slanting side
Area of the triangular sides =
= bh
= 4×3
= 12 square feet
Area of the rectangular base = Length × Width
= 4 × 8
= 32 square feet
Area of the vertical side = Length × Width
= 3 × 8
= 24 square feet
Area of the slanting side = Length × width
= 8×5
= 40 square feet
Total surface area = 12 + 32 + 24 + 40
= 108 square feet
Option (3) will be the answer.
