Answer:
b, d, and e
Step-by-step explanation:
those are the three answers
Secx =
As we know secx = hypotenuse/ perpendicular
And cotx = Base / perpendicular
So now we have to find BASE .
625=
+ 576
= 625 - 576
= 49
Taking squre root on both sides.
B = 7
Now cotx = 24/ 7
SO YOUR ANSWER IS OPTION . (C)

Answer:
There are 81 girls.
Step-by-step explanation:
First, take what we know and find how many people 1 in the ratio is:
54 / 2 = 27
(in this problem) 1 = 27
Now find how many girls are at the dance by multiplying by three:
27 x 3 = 81
There are 81 girls at the dance.
The answer is <span><span><span>x</span></span></span>³<span><span>+<span>9<span>x</span></span></span></span>²<span>+<span>27x</span></span>+<span>27</span>
Let, the number of students = x
Number of teachers = y = 6
Equation would be: 6x + 8.5y = 250
6x + 8.5(6) = 250
6x + 51 = 250
6x = 250 - 51
x = 199 / 6
x = 33.16
Students can't be in fraction, so after rounding-off, it will be 33
In short, Your Answer would be 33 Students
Hope this helps!
