Hoped this helped chu lol
You first simplify
tan(x) = cos(x)/sin(x) and cot(x) = sin(x)/cos(x)
Then you plug that in and then you simplify even more
So the figure is called a ray. Which is when there’s a point and than an arrow extends off that point forever. But the way to write a ray is by putting an arrow above it.
Answer:
BC = 1.71
Step-by-step explanation:
well to start we have to know the relationship between angles, legs and the hypotenuse in a right triangle
α = 70°
a: adjacent = BC
h: hypotenuse = 5
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, adjacent, hypotenuse)
we look at which meets those data between the sine, cosine and tangent
is the cosine
cos α = a/h
Now we replace the values and solve
cos 70 = a/5
0.34202 = a/5
0.34202 * 5 = a
1.7101 = a
round to the neares hundredth
a = 1.7101 = 1.71
BC = 1.71
