Answer:
1 equilateral triangle
Step-by-step explanation:
Given
Shape: Equilateral Triangle
Side length = 8cm
Required
Determine the number of triangles
From the question, we understand that the triangle is equilateral and the length of a side is 8cm.
This implies that the length of other sides will also be 8cm.
So, only one triangle can be constructed and their side lengths is 8cm.
Answer:
30° or 60°
Step-by-step explanation:
Range of a projectile on level ground is:
R = v₀² sin(2θ) / g
Given R = 15 m and v₀ = 13 m/s:
15 m = (13 m/s)² sin(2θ) / (9.8 m/s²)
sin(2θ) = 0.870
2θ = 60.4° or 119.6°
θ = 30.2° or 59.8°
Rounded, the launch angle required is either 30° or 60°.
Answer:
x = 1
Step-by-step explanation:
8 - 2x = -8x + 14
combine like terms:
- 2x + 8x = 14 -8
simplify:
6x = 6
x = 6/6
x = 1
