➷ As the two lengths are a, this means it is an isosceles triangle.
The two unknown angles would be equal so we can calculate them:
(angles in a triangle equal 180 degrees)
(180 - 90) / 2 = 45
Now we can use the sine rule to calculate the length a
(6 / sin(90)) x sin(45) = a
a = 4.242640687
To one decimal place, your answer would be:
a = 4.2mm

Answer:
.753
Step-by-step explanation:
Let Ps = probability both marbles are the same color.
Let Pd = probability both marbles are a different color.
Pd = 1 -Ps
Let Pb = probability both marbles are blue
Let Pr = probability both marbles are red.
Let Pg = probability both marbles are green
Pb= 2/9 * 1/9 = 2/81
Pr= 4/9 * 3/9 = 12/81
Pg=.3/9 * 2/9= 6/81
Ps = Pb + Pr +Pg= 20/81
Pd =1-Ps= 61/81 = .753
Is this correct?
Find two numbers that multiply to be 20 and add up to be -12. The question
5 x 4 = 20
2 x 10 = 20
20 + -32 = -12
good luck!!!
