An angle measures 2.2° less than the measure of its complementary angle. What is the measure of each angle?

Pie

Answer:

28 and 62

Step-by-step explanation:

complementary angles add up to 90o

x+(x-34) =90

2x-34=90

2x=56

x=28 (small angle)

28+34=62 (big angle)

A bag contains 3 red marbles 4 blue marbles and 7 Green marbles if two marbles are drawn out of the bag what is the probability

mr_godi [17]

Answer:

0.368

Step-by-step explanation:

Number of red marbles= 3

Number of blue marbles= 4

Number of green marbles= 7

Total number of marbles= 3+4+7= 14

Let the first ball is taken out to be red

P(R)= $\frac{3}{14}$

than again a second ball is drawn, number of balls left= 14-1=13

Number of red= 2

P(R)= $\frac{2}{13}$

Total probability= $\frac{3}{14}$ + $\frac{2}{13}$

Total probability= 0.368

Hence, the correct answer is 0.368
