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>

Answer:
is the required equation.
The Per sq ft of sheet costs $ 27.31.
Step-by-step explanation:
The total amount of sheet purchased = 8.8 sq. ft
The amount of sheet used = 2. 1 sq ft.
The worth of remaining sheet = $183
Let us assume the cost per sq ft of sheet = $x
Now, the remaining sheet =
Amount of total sheet purchased- Amount of sheet used
= 8.8 sq. ft - 2. 1 sq ft. = 6. 7 sq. ft
So, the worth of the remaining sheet 6.7 sq ft is $183.
⇒ Worth of 1 sq ft of sheet = $183 /6.7 sq ft
or,
or x = $27.31
Hence, the Per sq ft of sheet costs $ 27.31.
