A = 2.76 x 10^12 = 27600000000
w = 4.6 x 10^5 = 460000
w x l = A
2760000000000/460000 = 6000000
l = 6000000
(w x 2) + (l x 2) = perimeter
((4.6 x 10^5) x 2) + ((6.0 x 10^6) x 2) = 12920000

ANSWER: perimeter = 129.2 x 10^5

krok68 [10]

Answer: 250 miles

Step-by-step explanation:

I am not sure what grade level you are, but this is how it is done in college.

I hope it can give you an idea and be of some help.

First you have to convert 150 minutes to hours. Then you multiply your new hours to 100 miles.

150 minutes x <u> 1 hour </u> x<u> 100 miles </u>= 250 miles

Suppose a triangle has two sides of length 33 amd 37, and that the angle between these two sides is 120°. What is the length of

jeka57 [31]

Answer:

c = 60.65 cm

Step-by-step explanation:

Given that,

The two sides of a triangle are 33 cm and 37 cm.

The angle between these two sides is 120°.

We need to find the length of the third side of the triangle. Let c is the third side. Using cosine rule,

$c^2=a^2+b^2-2ab\cos C$

a = 33 cm, b = 37 cm and C is 120°

So,

$c^2=(33)^2+(37)^2-2\times 33\times 37\cos (120)\\\\c=60.65\ cm$

So, the length of the third side of the triangle is 60.65 cm.
