(csc x-1)(csc x+1)=csc²x-1²=csc²x-1=(1/sin x)² -1=1/sin x² - sin²x/sin²x=
=(1-sin²x)/sin² x = cos² x/ sin² x = (cos x/sin x)²= (cot x)²
Answer:
area of the rectangle =
Step-by-step explanation:
width = x cm
length = x + 5 cm
Perimeter = 2(length + width)
width = 7.5cm
length = 7.5 + 5 = 12.5cm
Area of the rectangle = length × width
