Answer:

x = 14.1 (Rounded to the nearest tenths)

Step-by-step explanation:

Since the opposite side of the angle given needs to be found out and hypotenuse, Sin ratio would be used;

Sin(42) = \frac{x}{21}

=> Now multiply 21 on both sides of =, in order to isolate x;

Sin(42) * 21 = x

14.1 = x

Hope this helps!

Answer:

14.1 =x

Step-by-step explanation:

Since this is right triangle, we can use trig functions

sin theta = opp/ hypotenuse

sin 42 = x /21

21 sin 42 = x

14.05174273 =x

Rounding to the nearest tenth

14.1 =x

Who walks at a faster rate? Makenna who walks 60 feet in 10 seconds or Christian who walks 576 inches in 6 seconds?
frez [133]
Christian because Makenna is going at a rate of 6ft/1s while christian is going at a rate of 8ft/1s
I got christians rate by dividing 576/12, which is 48 and i put 48/6 and 6x8 is 48 so when you divide its 8ft/1s

Light travels 300,000 km/s. The planet Mars is about 228,000,000 km from the sun. How would you find out how many minutes it tak
miv72 [106K]

Answer:

12.67 minutes

Step-by-step explanation:

Time taken is given by distance divided by speed

Given distance of 228, 000, 000 km and speed of light as 300, 000 km/s then time will be

Time=228, 000, 000/300, 000=760 seconds

Conversion

60 seconds make up 1 minute

760 seconds will be 760/60

Time=760/60=12.666666666666

Rounded off, this is 12.67 minutes

kobusy [5.1K]

Answer:

85%

Step-by-step explanation:

We have 30, 35, and 20.

Your question is asking what the total percent is. Since these percents are all on only a single item, we can just add them together.


30 + 30 = 60

60 + 25 = 85

There we go! 85%

<u>Brainliest</u> would be awesome.

Your Welcome, and thanks in advance.
