You have to square the whole thing so you will have:
(-3X x -5Y^4)(-3X x -5Y^4)

Then you use foil factor method and you will get the answer:
9X^2 + 25Y^8

Since beta is in the first quadrant, the final answer will be positive.

To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that

$\sin( \beta ) = \frac{ \sqrt{17} }{5}$

So, this means that

$\sin( \frac{ \beta }{2} ) = \sqrt{ \frac{1 - \frac{ \sqrt{17} }{2} }{2} } = \sqrt{ \frac{2 - \sqrt{17} }{4} } = \frac{ \sqrt{2 - \sqrt{17} } }{2}$

In circle T, PTQ = RTS. What is the measure of PQ? 24° 33° 48° 66°

weqwewe [10]

Answer:

The correct option is D

66°

Step-by-step explanation:

Given that ∠PTQ ≅ ∠RTS

The measure of the arc SR = 66°

So ∠RTS = 66°

But also, ∠PTQ ≅ ∠RTS

Therefore ∠PTQ = 66°

and the measure of the arc PQ = ∠PTQ

Therefore, measure of the arc PQ is 66°.
