Answer:
soh cah toa
to find a use sin =opp/hyp
sin 32=opp or a /hyp
sin 32*hyp=9.53
then to find b you can pythagorean theorem or just use cah or cos =adj/hyp
same process as above only using cos instead of sin
you get 15.3
then a^2+b^2=c^2
9.53^2+15.3^2=18^2 just to check or to use to find either a or b given c and either a or b

Answers
9514 1404 393
Answer:
x = 2/3, -1/4
Step-by-step explanation:
The zero product rule tells you a product will be zero only if one or more factors is zero. The solutions to this equation are the values of x that make one or the other of the factors be zero.
3x -2 = 0
3x = 2
x = 2/3 . . . . makes the first factor zero
__
4x +1 = 0
4x = -1
x = -1/4 . . . . makes the second factor zero
__
The solutions are ...
x = 2/3 or x = -1/4

g(x) = -10x2 + 490
lesser =
greater x =
Answers
Answer:
Lesser = -490
Greater x = 100x
Step-by-step explanation:
The zeros is basically the opposite numbers to make the equation equal to 0.
We have -10x^2(I believe it's a power)
and we have + 490
so,
-10x^2 = -100x
So the opposites to make those is:
+ 100x because, -100x + 100x = 0
and -490 because, 490 - 490 = 0.

Charles and Seth are building a ramp for Sasha and Samantha. The base of the triangle is 11ft and it's height is 5ft. How long is the diagonal of the ramp?
Answers
Answer: 12.1 ft
Step-by-step explanation:
A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.
c² = a² + b²
Where:
c = hypotenuse
a = base
b = Height
c² = 11² + 5²
c² = 121 + 25
c² = 146
c = √146
c = 12.1 ft

Find the value of x. If needed round to the nearest tenth (one decimal place)
Answers
Answer:
x = 8.7
Step-by-step explanation:
The triangles are congruent, which means that the sides are proportional to each other. Line DE and line BE are proportional to each other. This means that:
8 = 12
We can simplify this down to
2 = 3
Now that we have this proportion we can apply it to Lines AE and EC
2(13) = 3x
26 = 3x
8.67 = x
Therefore x is equal to 8.67 (or 8.7 rounded)
Check:
8/12 = 0.6667
8.6667/13 = 0.6667
Since both are the same, the answer is correct.
I hope this helps!!

Tiles with the letters A, B, C, D, E, F, G, and H written on them are placed in a bag. Malik draws out one letter at random. Which statements about the situation are true? Check all that apply.
The number of possible outcomes is 8.
The probability of drawing the tile with E written on it is 1/4
P(vowel) = 1/4
P(vowel) + P(consonant) does not = 1
Choosing one letter at random is a simple event.
Answers
Answer:
P(vowel) = [tex]\frac{1}{4}[/tex]
Choosing one letter at random is a simple event.
Step-by-step explanation:
P(vowel) = [tex]\frac{1}{4}[/tex]
This is because there are 2 vowels so the probability [tex]\frac{2}{8}[/tex] is which can be simplified to [tex]\frac{1}{4}[/tex] .
Moreover, Choosing one letter at random is a simple event.
The definition of a simple event is one that can only happen in one way, or in other words, it has a single outcome.
Malik's probability of drawing one letter at random is 1/4.
Probability calculation:P (vowel) = [tex]\bold{ \frac{1}{4}}[/tex] It's good to select one letter at random. P(vowel) = [tex]\bold{ \frac{1}{4}}[/tex]Since there are two vowels, the probability is [tex]\bold{ \frac{2}{8}}[/tex], is equal [tex]\bold{ \frac{1}{4}}[/tex].Furthermore, picking one letter at random is an easy procedure.A simple event is one that can only happen one way or has just one conclusion.Find out more about the probability here:
