Answer:

c = 730 cm

Step-by-step explanation:

To solve this question we just need to use the law of sines:

The ratio between a side in the triangle and its opposite angle is always the same.

So we have that:

a / sin(A) = c / sin(C)

714 / sin(78) = c / sin(90)

sin(78) is equal 0.9781 and sin(90) is equal 1, so we have:

714 / 0.9781 = c / 1

c = 714 / 0.9781 = 730\ cm

How many times larger is 5 × 106 than 5 × 102?<br><br>PLEASE HELP !
Ray Of Light [21]

Divide the largest one by the smallest one : for example, the number 4 is 42=2× larger than the number 2.

Indeed, If you multiply 2 by 42 you'll get 4.

Of course, if a number is n× larger than another, then this other is n× smaller than the first one.

It will of course work with floating point : 0.6×10.6≈0.6×1.6667=1 so 1 is ~1.6667 times larger than 0.6 while 0.6 is ~1.6667 smaller than 1.

Jahyib has 421 dollars. He has 152 dollars more than kelsyann. How much money do Jahyib and Kelsyann have altogether?
zaharov [31]
Both of them together have 690 because you subtract 152 from 421 so...

421-152=269

Then add 269 to 421

421+269=690
