Find the value of y.

Answer:

\Huge\boxed{B.18.610}

Step-by-step explanation:

Hello There!

We can find y by using trigonometric ratios

sine, cosine and tangent

tan= \frac{opposite}{adjacent}

the opposite of the angle that has a measure of 28 degrees is y and the side that is adjacent to the angle is 35

so...

tan28=\frac{y}{35}

now we solve for  y using basic algebra

we want to isolate the variable (y) using inverse operations

to get rid of the 35 we multiply each side by 35

\frac{y}{35} =y\\tan28*35=35tan28

now we let the calculator do the rest of the work

35tan(28)=18.60983011

*round to the nearest thousandth*

we're left with

y = 18.610

hence your answer is B

However the Triangle is then translated 4 units up, so the New and Final coordinates for Triangle ABC is A(-3,3) B(-1,0) and C(-2,4)

Hope this helps

6 pounds will cost $17.88

If you set up a proportion like this: 7.45/2.5=?/6, then all you have to do is cross multiply. 6x7.45 is 44.7, then 44.7 divided by 2.5 is 17.88
