The plane is 2 dimensional because it has height and width, which is a total of 2 dimensions.
The third choice is your answer since it is the only choice that has the proper dimension along with the proper explanation.
Have an awesome day! :)

Answer:
P ≈ 48.89°(nearest hundredth)
Step-by-step explanation:
The triangle PQR forms a right angle triangle since angle R is 90°. The triangle has an hypotenuse , adjacent and opposite side.
Using the SOHCAHTOA principle one can find the sine ratio of angle P. Let us designate where each side represent.
opposite side(QR) = 55
adjacent side(PR) = 48
hypotenuse(PQ) = 73
sin P = opposite/hypotenuse
sin P = 55/73
P = sin⁻¹ 55/73
P = sin⁻¹ 0.75342465753
P = 48.8879095605
P ≈ 48.89°(nearest hundredth)
Answer:
The answer to your question is 75 cm
Step-by-step explanation:
Data
Student calculator Demonstration calculator
width = 15 mm width = 4.5 cm
height = 250 mm height = ?
Process
1.- Convert the width of the demonstration calculator to mm
10 mm ---------------- 1 cm
x ---------------- 4.5 cm
x = (4.5 x 10) / 1
x = 45 mm
2.- Use proportions to find the height of the demonstration calculator
250 / 15 = x / 45
- Solve for x
x = (250 x 45) / 15
-Simplification
x = 11250 / 15
-Result
x = 750 mm
3.- Conclusion
The height of the demonstration calculator is 750 mm or 75 cm
