PLEASE HELP FINDING y IN TRIANGLE AND ROUND TO NEAREST TENTH TRIG!! HELP ASAP APLEASE

polet [3.4K]

Answer:

<em>y = 12.3 cm</em>

Step-by-step explanation:

This is a right triangle, so we can use sin,cos, or tan to solve this.

First, with respect to the angle 35 degrees, we can say "y" is the "adjacent side".

Also, the hypotenuse is given as 15.

<em>Which trig ratio relates adjacent and hypotenuse? That is COS. So we can write and solve the equation below:</em>

<em> $Cos(35)=\frac{y}{15}\\y=Cos(35)*15\\y=12.29$ </em>

<em />

<em>Rounded to 1 decimal place (nearest tenth) , </em>

<em>y = 12.3 cm</em>

What is the equation of the line?

kompoz [17]

A line has an equation of a form,

$y=ax+b$

From a graph we can pick two points on the line, say A and B where,

$A(x_1,y_2),B(x_2,y_2)\longrightarrow A(0,0),B(1,-1)$

Using their coordinates we are able to calculate slope.

$a=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-0}{1-0}=-1$

Hence,

$y=-1\cdot x+b$

The x and y terms can be replaced with coordinates of one point either A or B. I'll pick A.

$0=-1\cdot0+b$

And now solve for b.

$0=0+b\Longrightarrow b=0$

Hence,

$y=-1\cdot x+0$

Simply,

$\boxed{y=-x}$

Hope this helps.

I believe the answer is the first one because it contains a negative fraction and in the chart some of the numbers are negative
