!!!!Cosines / sines . Find a and round to the nearest 10th.
nadya68 [22]

I think Erica said I messed this one up. It looks the same. Oh yeah I think this was the one I thought a=1.8=3\sqrt{2}-\sqrt{6}, Answer: 1.8.

Let's do it again.

\dfrac{a}{\sin(180 - (15+105))}=\dfrac{2}{\sin 105^\circ}

a = \dfrac{2 \sin(60)}{\sin 105^\circ}

a \approx 1.8

Yes, same as before.

What is the slope and y-intercept of the line y - 2x = 8
zysi [14]

Answer:

Slope is 2x and y-intercept is 8

Step-by-step explanation:

First you have to get y all by itself on the left side of the equal sign. To do that, you must add 2x on both sides. You will get: y=2x+8.

Probability of rolling factors of 20
Marizza181 [45]
If you are rolling a single six sided die numbered 1-6, you find that only 1,2,4, and 5 are factors of 20. Now the theoretical probability of an event is the ratio comparing the number of desired outcomes to the total outcomes possible.

In this case: we have 4 desired outcomes out of a total 6 outcomes possible with a single roll the die.. therefore, the probability you seek is \frac{4}{6} = \frac{2}{3} or approximately 67%.
