I'm gonna need some sort of diagram...
Answer:
x =
, y = 2
Step-by-step explanation:
using the tangent ratio and the exact value tan45° = 1 , then
tan45° =
=
= 1 , then
x = 
----------------------------------
using the cosine ratio in the right triangle and the exact value
cos45° =
, then
cos45° =
=
=
( cross- multiply )
y =
×
=
= 2
Answer:
Remember: minus a minus is a plus:
=11
Step-by-step explanation:
It’s A I think I had it on a recent test :) I’m not sure tho
The electric currents and magnetic materials have an
effect called magnetic field. This magnetic field is specified with its
direction and magnitude. The magnitude is the strength of the field.
the magnetic field at a distance r from a
long straight wire carrying current I can be calculated with the
equation:
B = μ I / 2 pi R
where <span>μ is a constant, I is the current and R is the radius. </span>
