The answer is c- 7+yx(+8)-24
The equation for cosine is the adjacent/hypotenuse. Looking at our L, the letter right next to it is the lowercase l, so that is the adjacent. The hypotenuse is always the side opposite the right angle, so the hypotenuse in this question is the lowercase m. The answer for the first question, then, is k/m. For the second question, you are asked to find the side of q. In questions like these, always start from the angle given to you. Start from the 51 degrees. Right next to the 51 degrees is q, so q is the adjacent. We also have a number, 134, which is opposite the given angle 51. Now use the trigonometric ratio that involves adjacent and opposite, which is tan. Therefore, tan51 is the right answer. Hope this helps! Ask me for more help.
There are two Right angled triangles in the given figure, with two missing sides, let's name the other missing side be " y "
According to Pythagoras theorem,
note :
- p = perpendicular / opposite side
- b = base / adjacent side
- h = hypotenuse
let's solve for " y² " first ( square of other missing side )
now let's solve for " x " , by using pythagorous theorem
Approximate :
Answer:
27 girls and 15 boys
Step-by-step explanation:
To solve this, I just used guess and check.
9:5 is a ratio, which means we can multiply each side by any number as long as we do it to both sides.
If we multiply the ratio by 3, we get (9 x 3) : (5 x 3) which is 27:15
And as it turns out, 27-15 is 12, which in this context means there are 12 more girls in drama club, so it works out.
