Find the sizes of the angles marked with a letter.<br> Why is my answer wrong?
jeyben [28]

Answer:

29.28 degrees.

Step-by-step explanation:

sin x / 16.2 = sin 49 / 25

Cross multiply:

25 sin x = 16.2 * sin 49

sin x = (16.2 * sin 49) / 25

sin x = 0.48905

x = 29.28 degrees.

Does anyone know how to solve a system of linear equations using elimination? I am having a hard time on how to do it for differ
Mariana [72]
1. Multiply each equation so they end up with the same coefficient

2. Subtract your second equation from the first

3. Solve for one of the variables (I tend to solve an equation that only contains 2 variables if possible. So it would be if you have one question with x and y, solve for the easier one)

4. Substitute the variable you found in the least step into one of the other equations and find a second variable.

5. Substitute both variables you found into the last equation and there you should be left with x, y, and z :))

I hope this helped sksjsk if it didn’t I could write it out to hopefully help more :)

An animal shelter spends three dollars per day to take care for each bird and seven dollars per day take care for each cat Alexa
NikAS [45]

Answer:

There were 16 birds  at the shelter on Wednesday.

Step-by-step explanation:

Number of cats and birds on Wednesday = 34

let the number of birds on Wednesday = b

Then number of cats = (34 -b)

The rate of taking care of each bird in shelter = $3

The rate of taking care of each cat in shelter = $7

Total amount spent by shelter on Wednesday = $174

So, according to the question

b x ($3)  +  (34 -b) ($7) =  $ 174

or,  3b + 238 - 7b = 174

or, 4b = 64

⇒ b = 64/4 = 16

Hence, the number of birds in shelter on Wednesday = b = 16

and  Number of cats = 34 - 16 = 18
