By using what we know about right triangles, we will see that the height is 11.7 m.
<h3>How to find the height of the tower?</h3>
We can view this as a right triangle, such that the wire is the hypotenuse of said triangle.
We know that the hypotenuse measures 14 m, and the angle between the ground and the wire si 57°. The height would be the opposite cathetus to that angle, so we can use the rule:
Sin(a) = (opposite cathetus)/hypotenuse
Replacing the values we get:
Sin(57°) = H/14m
Sin(57°)*14m = H = 11.7m
The height of the tower is 11.7 meters.

Answer:
they need to sell 60 sweaters
10 more than 50
Step-by-step explanation:
20% of 100 is 20
20% of 50 is 10
20 divided by 2 equals 10
Answer:
Step-by-step explanation:
the circle is at the origin and (0,4) is a point on the circle then the radius of the circle is:
r^2=0^2+4^2
r^2=16
r=4
so we can check that the other point is four units from the origin and thus also on the circle...
d^2=2^2+6^2
d^2=4+36
d^2=40
since d^2>r^2, (2,6) is outside the circle
Answer:
A) -4
Step-by-step explanation:
f(x)=10-2x
