The area below x = -3 should be shaded to show that x < -3.
Answer:
m<2 = 50°
Step-by-step explanation:
Right triangle
m<3 = 40
so m<2 = 90 - m<3
m<2 = 90 - 40
m<2 = 50
Answer:
X has the coordinates of (-2, 1).
Step-by-step explanation:
Answer:
The length of the rope = 8.94 meters
Step-by-step explanation:
∵ The flagpole is 8 meters high
∵ The hook is 4 meters from its base and the hook is in the ground
∵ The flagpole and the ground ⊥ to each other
By using Pythagoras theorem:
∴ The length of the rope = √(8² + 4²) = 5√5 = 8.94 meters
