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>
