Csc x · sec x - tan x =
= 1 / sin x · 1 / cos x - sin x / cos x =
= 1 / sinx cos x - sin² x / sin x cos x =
= ( 1 - sin² x ) / (sin x cos x) =
= cos² x / ( sin x cos x ) =
= cos x / sin x = cot x
Answer:
x=20
Step-by-step explanation:
we know the straight angle theorum...
3x+80+2x=180
5x=100
x=20

We need to cut a 15m rope into 20 equal pieces. Written mathematically, it is as follows:
15/20 = length of rope segment in meters (a)
15/20 = a
Simplify
3/4 = a
In meters, each rope segment is 3/4m long. But, we don't want meters. We want centimeters.
100 cm = 1 m
3/4(100) = length of rope segment in centimeters (x)
3/4(100) = x
300/4 = x
75 = x
Each segment of rope is 75 cm long.
The correct standard form of the equation of the parabola is:
= 4(y - 3).
<h3 /><h3>What is a parabola?</h3>
An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively. It's also crucial to remember that the fixed point is not located on the fixed line. A parabola is a locus of any point that is equally distant from a given point (focus) and a certain line (directrix). An essential curve of the coordinate geometry's conic sections is the parabola.
For the given question,
Vertex of parabola is (-3,3)
Thus, the equation of the parabola is:
= 4(y-3)
