Answer:
59 degrees
Step-by-step explanation:
In the figure below, XZ is a diameter of circle A.
Since the Angles (5w+4) and (11w) forms a straight line, then:

Therefore, the arc measure of YZ will be:

Ah, one of my FAVORITES!
1. Take 2 points, ill take (0, 0) and (4, 12)
2. Set them as "1" and "2" so (0, 0) be 1 and (4, 12) be 2.
3.

and insert the equations.
4. You get

which simplifies to

.
5.

=3
6. Slope = 3
Hope this helps ^^
we know that
The scale factor is equal to

we have

substitute


therefore
<u>the answer is</u>

Given:
- Bought n items of product A at 1/5 rs each
- bought n items of product B at 1/4 rs each
He mixed the two items and sold each at 2/9 rs each.
He lost 3 rs in the above batch of articles.
Solution:
revenue = 2n* (2/9) rs = 4n/9 rs
cost = n/5+n/4 rs = n(1/5+1/4)
Profit = revenue-cost = 4n/9-n(1/5+1/4) = -3 rs
Solve for n
4n/9-n(1/5+1/4) = -3
factor out n
n(4/9-1/5-1/4)=-3
n(80-36-45)/180=-3
-n/180=-3
n=3*180=540
Total number of products bought
= n+n = 540+540 = 1080
That would be well.. that would be B. 4
