Your answer is C lmk if that helps!
13 times 3 equals 39. So 13 and 3 are the two numbers.
Applying the trigonometry ratios, the correct option is: B. none of these are correct.
<h3>What are the Trigonometry Ratios?</h3>
The trigonometry ratios are SOH CAH TOA, which are used for solving a right triangle.
Use the trigonometry ratio to find out which option is correct.
Cos Z = adj/hyp = 61/CZ, so option A is incorrect.
Sin Z = opp/hyp = 73/CZ, so option C is incorrect.
Tan Z = opp/adj = 73/61, so option D is incorrect.
Thus, the answer is: B. none of these are correct.

Answer:
This is experimental fraction question
We start with a high fraction and work downwards to a lower fraction
Reduce 10/16; = 6/12 = 1/2 observation = the fraction gets smaller by 1/5
Reduce 10/12 = 6/9 = 1/3 observation = the fraction gets smaller by 1/4
Reduce 8/8 = 3/2 observation = the fraction gets smaller by 1/3
We notice that when the fraction is whole number it reduces by 1/3
When the fraction is 3/4 it reduces by 1/4
When the fraction is 5/8 or 10/16 it reduces the fraction by 1/5
When the fraction is already half
We can prove it reduces again by a smaller than 1/5 number
1/2 = 10/20 = reduction = 6/15 = it has reduced by 3/15 = 1/6 to 1/7
This is because the numerator is reduced 40% and the denominator is reduced by 25%
Step-by-step explanation:
30 degrees
Angles ACB and CAB are both 75 degrees due to the fact that they are 90 degree angles subtracting the 15 degrees. Then add the two together and subtract from 180.
