I would go with
Surveys
Because it's a great way to get the opinions of a lot of people
Hope that helps :)
21/35 = x/100
cross multiply
2100=35x
x = 60
Use Pythagoras theorem
10^2 = (8/2)^2 + h^2
(3x-4)(X+1)
3x(X+1)
3x times X =3X^2
3x times 1= 3x
-4(X+1)
-4 times X = -4X
-4 times 1= -4
3X^2+3X-4X-4
Add the middle ones
3X^2-X-4
Solve for x given two sides
Solution
x is an angle hence we are gonna use the formula Sin
Sin 0 = opp/hyp
0 represents theta.
Sin 0 = opp/hyp
Sin 0 = 27/33
Put 27/33 in decimal form
= 0.8181
Transpose to make 0 the subject
Sin 0 = 0.8181
0 = Sin-1 0.8181
When adding Sin from one side to another it becomes Sin inverse.
0 = Sin-1 08181
Now we find the answer
0 = Sin-1 0.8181
= 54.89 degrees
Therefore x is equal to 54.9 to the nearest tenth.
