There are several ways to solve this, but the law of sines is probably the easiest...

Law of Sines:  sina/A=sinb/B=sinc/C  for any triangle...in this case we can say:

sin48/x=sin90/55

xsin90=55sin48

x=55sin48/sin90

x≈40.873  (to nearest one-thousandth, not sure which precision you needed)

Write 44 as a product of prime factors.
Ann [662]

<u>Answer:</u>

  • Hence, 11 x 2 x 2 is the product of prime factors.

<u>Step-by-step explanation:</u>

<u>Let's divide by 2's.</u>

  • => 44 = 22 x 2
  • => 22 x 2 = 11 x 2 x 2

<em>Since 11 is a prime number, we cannot simplify it anymore. Hence, 11 x 2 x 2 is the product of prime factors.</em>

What is (2.3x10^-3)/(4.6x10^-7) written in scientific notation? Please show how you solved this.
lions [1.4K]
(2.3*10^-3) / (4.6*10^-7)

(2.3*0.001) / (4.6*0.0000001)  *10^-3=0.001 & 10^-7=0.0000001*

(0.0023) / (0.00000046)   *2.3*0.001=0.0023 & 4.6*0.0000001=0.00000046*

5000  *0.0023/0.00000046*

So the answer is 5000
