Answer:
1) B = 66.5° c = 10.9
Step-by-step explanation:
I will do question one as an example. In general, for these questions you want to use the appropriate trigonometric ratios to solve for the variables and/or apply logic using rules regarding triangles. See attached image for all solving steps.
For side c, we can use Cosine of angle A for a ratio between 10 and c. When we write out the equation, we can solve for side c. So when we write it out, we get the equation:
cos23.5 = ¹⁰⁄c
c = ¹⁰⁄cos₂₃.₅
c = 10.9044 (make sure to round to the nearest tenth, which is one decimal place)
For angle B, since they have given two angles, you can solve for B since all angles of a triangle add up to 180 degrees.
So b = 180 - (90 + 23.5) = 180 - 113.5
b = 66.5
- It is also possible to solve this using sine of angle B and solve it from there, but applying the theory this way is much simpler. (this is on the image if you're curious about it)
I hope this helps you with the other 3 questions.
Answer:

Step-by-step explanation:
Store A:
5 bagels for $2.05, 1 bagel for $2.05/5 = $0.41.
Store B:
3 bagels for $1.35, 1 bagel for $1.35/3 = $0.45.
Hence the bagels at Store B are $0.04 more expansive than the bagels at Store A. (C)
Answer:
Its 4/10
Step-by-step explanation:
You get 4/10 because there are 10 rows and 10 columns. 10*10 is 100. 40 0f them are shaded so it would be 40/100. You need to simplify by dividing by 10 and you get 4/10.
