Answer:

a=40

b=50

c= 115

Step-by-step explanation:

The first angle we will find is angle c

65 and angle c make a straight line so they add to 180

c+65 = 180

Subtract 65 from each side

c+65 -65 =180-65

c = 115

Angle a and 40 are vertical angles

Vertical angles are equal

angle a = 40

The sum of the angles in a triangle are equal to 180

a+b+ right angle = 180

40+ b + 90 = 180

130 +b = 180

Subtract 130 from each side

130-130+b = 180-130

b= 50

A jar contains 2 green marbles, 4 blue marbles, and 3 yellow marbles. A marble is chosen at random from the jar and replaced. Fi

omeli [17]

Answer:

2/27

Explanation:

• Number of green marbles = 2

• Number of blue marbles = 4

• Number of yellow marbles = 3

Total = 2+4+3 =9

• Probability of choosing a green marble = 2/9

• Probability of choosing a yellow marble = 3/9

Therefore, the possibility that the first marble is green and the second is yellow is:

$\begin{gathered} =\frac{2}{9}\times\frac{3}{9} \\ =\frac{2}{27} \end{gathered}$
