We have that
sin ∅=-0.7660
the sin ∅ is negative
so
∅ belong to the III or IV quadrant
but
180°< ∅ < 270°
hence
∅ belong to the III quadrant
sin ∅=-0.7660
sin² ∅+cos² ∅=1
cos² ∅=1-sin² ∅------> cos² ∅=1-(0.7660)²-----> 0.4132
cos ∅=√0.4132-----> cos ∅=0.6428
the value of cos ∅ is negative-------> III quadrant
cos ∅=-0.6428
tan ∅=sin ∅/ cos ∅----> tan ∅=-0.7660/-0.6428----> tan ∅=1.1917
the answer is
tan ∅ is 1.1917
The greatest common factor of this can be solved by looking at the individual parts and splitting it up.
First, we have 28 and 7. Well, thats an easy one. 7 goes into 28 4 times so we are now left with 4 and 1.
We can also write the rest of this like this 4(x*x*y) - 1(x*y*y*y*y*y)
Now, what values are in both equations. We have one x and one y that can be taken out of both.
We end up with 7xy(4x-7y^4)
Hi there! :D
<em><u>Answer:</u></em>
<em><u>2(2a+5)</u></em>
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
First, rewrite the problem down 10, and then 4.
10=5*2 or 2*5
4=2*2
2*2a+2*5
Finally you had to factor out by the common term of 2.
2(2a+5)
Hope this helps!

4 hours and 15 minutes =4+15/60=4.25 hours
the average speed of the train = 250/4.25=58.82mph
A) 2 X 3 + 2 X 5 = 2 (3+5)
B) 5a + 5b - 5c = 5 (a+b-c)
C) ma - ab = a(m-b)
