It looks like you're missing some parentheses.
I think this is the equation you mean:
sin(x)/(1-cos(x)) + sin(x)/(1+cos(x))
your common denominator is (1-cos(x))*(1+cos(x)), which is the difference of squares simplification and is equal to (1-cos^2(x)) = sin^2(x)
Numerator: sin(x)*(1+cos(x)) + sin(x)*(1-cos(x))
= sin(x) +sin(x)cos(x) + sin(x) - sin(x)cos(x)
= 2sin(x)
Answer: 2sin(x)/sin^2(x) = 2/sin(x) = 2csc(x)
Answer:
To find simple interest you take
= Principal ×Rate ×Time ÷ 100
Perimeter of the triangle GHJ is 35cm.
<h3>What is perimeter?</h3>
A perimeter is a closed path that includes, encircles, or delineates a one-dimensional length or a shape with two dimensions.
The perimeter's units are equal to the sides of a polygon's length.
Given Data
The perimeter of a triangle is, by definition, the total length of its sides.
Next, the triangle LMK's perimeter is:
ΔLMK = 14+ 11 + 17
ΔLMK = 42
The perimeter of the triangle LMK must be multiplied by the scale factor if both triangles are congruent and the scale factor is 5:6 (which can be written as a fraction:
).
Next, you have that the triangle GHJ perimeter is:
ΔGHJ = 4(
)
ΔGHJ = 35
Perimeter of the triangle GHJ is 35cm.
