Answer:
<em>$40 </em>will be the total cost of the ribbon.
Step-by-step explanation:
To find the cost of ribbon to be put on the edges of rectangular banner, we need to:
1. Find the perimeter of the rectangle.
2. Multiply the perimeter with the per foot cost to find the total cost.
Let us find the perimeter first:
Perimeter of a rectangle is given as:
![P = 2 \times \text{(length+width)}](https://tex.z-dn.net/?f=P%20%3D%202%20%5Ctimes%20%5Ctext%7B%28length%2Bwidth%29%7D)
Here, the dimensions of rectangle are 4ft by 6ft.
So, perimeter = ![2 \times (4+6) \Rightarrow 20\ ft](https://tex.z-dn.net/?f=2%20%5Ctimes%20%284%2B6%29%20%5CRightarrow%2020%5C%20ft)
It is given that per foot cost is $2.
Total cost of the ribbon = ![2 \times 20 \Rightarrow $40](https://tex.z-dn.net/?f=2%20%5Ctimes%2020%20%5CRightarrow%20%2440)
<em>$40 </em>will be the total cost of the ribbon.
A,b are 8,2. its an easy guess.
now that makes it easy

Answer:
Step-by-step explanation:
take 50 degree as reference angle
using sin rule
sin 50 = opposite/hypotenuse
0.766 = x /3
0.766*3 = x
2.298 = x
2.30 = x
