Find the exact value
given that cos theta = 15/17 with theta quadrant 1 , find sin 2theta and cos 2theta
plzz

Since cos theta is 15/17, let a right triangle have a hypotenuse of 17 and a leg of 15. This means that the other is 8.

Sin 2 theta is a double angle identity.

Sin 2 theta  = 2 sin theta cos theta = 2(8/17)(15/17) = 240/289

Cos 2theta = cos^2 – sin^2 = (15/17)^2 – (8/17)^2 = 161/289

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
