Answer:

a=110 degrees

b=70 degrees

c= 50 degrees

d=130 degrees

Step-by-step explanation:

To find a know that 180 degrees is a straight line, and subtract 70 from 180 to get 110 degrees. To find b, know that the angles between parallel lines add up to 180, and if you know a is 110 you know b is 70. Then, find out c by knowing that all three angles of a triangle add up to 180, and you have 60 given and you found out b is 70, so you know c is 60 plus 70 which is 130 and 180-130 is 50 degrees. Lastly, to find d you need use the same strategy you used to find b( know that the angles between parallel lines add up to 180) and you get 130 degrees.

Answer:

$\large\boxed{\theta=-\dfrac{\pi}{4}+k\pi\ or\ \theta=k\pi}\ for\ k\in\mathbb{Z}$

Step-by-step explanation:

$\tan^2\theta+\tan\theta=0\\\\\tan\theta(\tan\theta+1)=0\iff\tan\theta=0\ \vee\ \tan\theta+1=0\\\\\tan\theta=0\Rightarrow \theta=k\pi\ \text{for}\ k\in\mathbb{Z}\\\\\tan\theta+1=0\qquad\text{subtract 1 from both sides}\\\\\tan\theta=-1\Rightarrow\theta=-\dfrac{\pi}{4}+k\pi\ \text{for}\ k\in\mathbb{Z}$

a cell phone company charges a monthly fee plus a 0.35 for text messages sent they charge 25.00 monthly fee and your bill is 58.

riadik2000 [5.3K]

Hey,

So first we are told that they charg a fixed fee of 25:00 right?That means even if you didn’t send any text messages you still have to pay 25:00.

So first we have to subtract that 25:00 form 58.25 right?This means the rest of the bill is for text messages OK?
So he spent 33.25(this is the answer to the subtraction) on the text messages right?
And for every text he sent he was charged 0.35 right? So we have to divide 33.25 by 0.35 right?
And that gets us 95.

Now we can double check the answer by multiplieng 95 by 0.35 and adding 25.

So th answer is 95

Hope this helps !!
