Answer:
3.32ft
Step-by-step explanation:
The wire and the poles attached to the ground form a right triangle with the length of the wire being the hypotenuse.
Using Pythagoras Theorem:
Hypotenuse²=Adjacent²+Opposite²
6²=5²+x²
x²=36-25
x²=11
x=√11=3.32 ft.
The wires are attached 3.32 ft from the base of the pole on the ground
Answer:
Yes they are
Step-by-step explanation:
In the triangle JKL, the sides can be calculated as following:
- J(2;5); K(1;1)
=> JK =
- J(2;5); L(5;2)
=> JL =
- K(1;1); L(5;2)
=> KL =
In the triangle QNP, the sides can be calculate as following:
- Q(-4;4); N(-3;0)
=> QN =
- Q (-4;4); P(-7;1)
=> QP =
- N(-3;0); P(-7;1)
=> NP =
It can be seen that QPN and JKL have: JK = QN; JL = QP; KL = NP
=> They are congruent triangles
