Area of triangle = base x height over 2
3 x 4 = 12
12 over 2 = 6
area = 6cm^2
Let x = angle we must find
tan x = 14/30
arctan(tan x) = arctan(14/30)
x = 25.0168934781
Answer: 25 degrees
Since there is a right angle, you can use Pythagoras' Theorem:
So x = √(24² + 7²) = 25

The probability of not drawing a red marble is 7/10
The probability of drawing a red marble is 3/10
=======================================================
Explanation:
We have 3 red marbles out of 5+2+3 = 10 total. Therefore, the probability of selecting a red marble is 3/10.
The probability of not selecting a red marble is 7/10 because 3/10+7/10 = 1. Put another way, we have 7 marbles that aren't red (the 5 blue and 2 black ones) out of 10 total.
Answer:
15/4 or 3 3/4
Step-by-step explanation:
since 1/5 has 1 as a numerator,
5 x 3/4=
15/4
it will take about 3 hours and 45 minutes
