For a chinese new year celebration, james and zhou are making a dragon costume similar to the one shown above.

in total, the costume requires 56.6 meters of fabric. zhou already has 15 meters of fabric, and james just purchased 17.6 meters of fabric. how much more fabric is needed for the costume?
a.
39 meters
b.
25 meters
c.
24 meters
d.
32.6 meters

C. 24 meters

Step-by-step explanation:

Given:

Total length of fabric required for the costume = 56.6 m

Length of fabric Zhou already has = 15 m

Length of fabric James just purchased = 17.6 m

To find how much more length of fabric is required to make the complete costume.

Solution:

Let the length of fabric in meters still required be  =

The total length can be given as :

⇒

⇒

The total fabric required = 56.6 m

So, the equation to find will be:

Subtracting both sides by 32.6

∴

Thus, 24 meters of fabric is still required to make the costume.

Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°
I hope it is helpful:D
