Convert R=(12)/4+8sin the theta to rectangular form

r=\dfrac{12}{4+8\sin\theta}=\dfrac3{1+2\sin\theta}

Let y=2\sin\theta, and recall that in polar coordinates, r=\sqrt{x^2+y^2}. This means you have

\sqrt{x^2+y^2}=\dfrac3{1+y}

You can stop there, or try to find something that looks somewhat nicer.

x^2+y^2=\dfrac9{(1+y)^2}

Answer:

1/2 - 3(1/2 + 1)²

simplify the expression (1/2 + 1)

1/2 - 3•(3/2)²

using PEMDAS, we see we have to evaluate the exponent first

(3/2)² = 9/4

rewrite the equation

1/2 - 3 • (9/4)

multiply 3 by (9/4)

1/2 - (27/4)

subtract

-25/4

(1 + 1/3)² - 2/9

simplify the expression (1 + 1/3)

(4/3)² - 2/9

using PEMDAS, we see we have to evaluate the exponent first

(4/3)² = 16/9

rewrite the equation

(16/9) - (2/9)

subtract

14/9

How to solve this triangle ABC?<br>i did super wrong all :( who can help me please?
Alex73 [517]

It looks like you had some of the numbers correct, but you just labeled it and rounded it incorrectly, and the teacher gave you super partial credit for it.  

For my work, I'm assuming that side A is opposite of angle A and side B is opposite of angle B, etc...
