Answer:
SinA = 40/50
Step-by-step explanation:
I think it's just asking if you understand the trig ratios. You aren't really solving for anything.
SinA is 40 over 50 because 40 is opposite of <A and 50 is the hypotenuse.
Then, use the trig ratios to figure out the other problems.
ANSWER—46
Step-by-step explanation:
*All the angles in a triangle add up to 180 degrees.*
Let The wanted angle be x,
Then x+98+36=180. Solve for x.
Dot plots are used for continuous, quantitative, univariate data. They can be also used for finding outliers, compare distributions, locate the central tendency of your data, etc…
The answer is (0,3)

First, you add up the total number of students because we would base our percentage one this.
Total number of students = 1+4+5+10+20+10+5
Total number of students = 55
Now, let's count how many of them got a score of more than 70. For this, you would only count the students belonging to 70-under 80, 80-under 90 and 90-under 100.
Students who got more than 70 = 20+ 10 + 5 = 35
Therefore the percentage is equal to:
Percentage = 35/55 * 100 = 63.64%
