galben [10]

Answer: 3/10 probability

Step-by-step explanation:

We are telling the probability with tenths, so we can say that the probability of the meteoroid landing on Earth is 3/10.

If the surface area of the world is approximately 7/10, or 70 percent, water, there is approximately 3/10, or 30 percent, chance of the meteoroid hitting land.

I'm pretty sure, at least ^_^

Find the value of x in the given figure
nlexa [21]

Answer:

20°

Step-by-step explanation:

To find ∠C you don't even need 90° unless you would want to check if you are correct. to find ∠C you would just look for the whole triangle, so basically A + B + C = 180.

80 + 30 = 110

180 - 110 = 70

∠C = 70

Then you would take 70° and subtract it to 90° since it is a right angle combined with x and you would get your answer which is 20°.
