ZX is one side out of the triangle
Step-by-step explanation:
CD = AB
the inner angle at C = 25° = the outer angle at A.
so, the inner angle at A = 90 - 25 = 65°
now we use the law of sine
a/sin(A) = b/sin(B) = c/sin(C)
with a, b, c being the triangle sides, and A, B, C the angles opposite of the correlated sides.
so, in our case
555/sin(65) = AB/sin(25) = CD/sin(25)
CD = 555×sin(25)/sin(65) = 258.8007503...
≈ 258.8 m

a) the Probability p( red, red, red) is 0.83%.
b) the probability p(white, red, white) is 0.
<u>Step-by-step explanation:</u>
The total number of marbles = 3+6+1.
=10.
a) to find the Probability p( red, red, red).
p( red, red, red)= 
p( red, red, red)=
×
×
.
p(red,red,red)= 0.0083.
p(red,red,red)=0.83%
b)to find the probability p(white, red, white).
p(white, red, white) is 0.
Since there is only one white.
