Prove tan3A= (cos(2A)-cos(4A))/ (sin(4A)- Sin(2A)) ...?

aivan3 [116]

The solution to the problem is as follows:

<span>cos2A - cos4A = -2 sin(6A/2).sin(-2A/2) = +2 sin(3A).sinA

and

sin4A - sin2A = 2 cos(6A/2).sin(2A/2) = 2 cos(3A).sinA

Hence RHS = (cos(2A)-cos(4A))/ (sin(4A)- Sin(2A)) = sin 3A / cos 3A = tan 3A = LHS
</span>

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Find the scale factor and ratio of perimeters for a pair of similar octagons with areas 36 ft squared and 49 ft squared.

vagabundo [1.1K]

Answer:

scale factor: 1.16

perimeters: 21.84 ft and 25.36 ft

Step-by-step explanation:

The area for an octagon is as follows:

$A = 2*l^{2}(1+\sqrt{2})\\$

solved for "l":

$l = \sqrt{\frac{A}{2*(1+\sqrt{2}) } }$

now we calculate the value of each side:

$l1 = \sqrt{\frac{36}{2*(1+\sqrt{2}) } }$

l1 = 2.73

$l2 = \sqrt{\frac{49}{2*(1+\sqrt{2}) } }$

l2 = 3.17

The scale would be:

3.17 / 2.73 = 1.16

And the value of the perimeter of the first would be:

2.73 * 8 = 21.84

and the second:

3.17 * 8 = 25.36
