Answer:
240 cm^2
Step-by-step explanation:
area of each triangle
=(10 x 7)/2 cm^2
=35 cm^2
area of four triangles
=35 x 4 cm^2
=140 cm^2
area of the square
=10 x 10 cm^2
=100 cm^2
area of the polygon
=(100 + 140) cm^2
=240 cm^2
312,000$.
I just found 60 percent of 520,000 so I hope that’s what you wanted, and I am truly sorry if it isn’t.
We are given two sides of a triangle that are 2 and 5 and the angle between them is pi/3 or 60 degrees. In this case, we can use the cosine law to relate the given dimensions and angle. The cosine rule goes c2 = a2 + b2 - 2abcos C; Substituting, c2 = 4 + 25 - 2*2*5*cos pi/3 ; c2 = 19; c = sqrt 19 = 4.36 units.
The 24 oz. is the better deal. For the 24 oz, each ounce is worth $.08 compared to $.10 per ounce for the 32 ounce bottle.
