Right scalene triangle is formed for given side lengths
Multiply both sides 2
2A=(A+B)H
Divide both sides by (A+B)
H=2A/(A+B)
40+10=50
180-50=130
10+20=30
180-30=15
angle at center add up to 360
360-(130+150)=80°
The triangle is an equilateral.
180-80=100
both base angles are 50°
We know that
g=3
r=2
b=5
total marbies=g+r+b------> 3+2+5----> 10
a) <span>probability that the first marble is red
P(red)=r/total marbies------------> 2/10-----> 1/5
b) </span><span>probability that the second marble is blue
in this case total marbles-------> 9
P(blue)=b/total marbles----------> 5/9
c) </span><span>the probability that the first marble is red and the second is blue
(1/5)*(5/9)=1/9
the answer is
1/9</span>
4 square meters equals 4.784 square yards
