By using sin you can find BD. Sin is the opposite side/ hypotenuse. This can be simplified to BD = opposite (4) divided by sin(27). 27 is the angle.
Answer:
#1 is 9 times 10^15
#2 is 3 times 10^8
Step-by-step explanation:
Answer: M{x°}=89
A triangle has 3 sides, and the total degree is 180°. So make a equation to find the third degree (x).
Answer:
- 20 -5k = 4
- the LCM of the denominators is 10
Step-by-step explanation:
I find it convenient to do the problem in the reverse order: find the LCM, then distribute. That way, I'm not distributing a fraction.
The LCM of 2 and 5 is their product: 2·5 = 10. Multiplying the equation by 10 gives ...
5(4 -k) = 4
Now, distributing, we get ...
20 -5k = 4
the width of a book is about ("25 x 20cm")
the length of a pencil is about 15cm (19cm if unsharpened)
