I didn't understand your question.
Simply you can substitute theta=45 degrees (or any angle,not zero) in left hand side and right hand side.
or
using a^2 - b^2 =(a+b)(a-b)
= sin(2x+x)sin(2x-x)
= sin 3x sin x
Answer: x=12y/-8-3
Step-by-step explanation: image below
Answer:
Given,
p (x)=2x-3
g (x)=6x+4
p (x)×g (x)=?
Step-by-step explanation:
p (x)×g (x)=(2x-3)(6x+4)
=2x (6x+4)-3 (6x+4)
=12x^2+8x-18x-12
=12x^2-10x-12
Answer:
496.6
Step-by-step explanation:
circumference of circle=8pie^2
2*pie*r=8*pie^2
2*r=8*pie
2r=8*22/7
r=176/7÷2
r=12.57
Area of circle=pie*r^2
=22/7*12.57^2
=22/7*158
=496.6
