Answer:

<COB = 50°

Step-by-step explanation:

We can say that m<AOC + m<COD + m<DOB = 180° because the three mentioned angles form a straight line. We can substitute to get:

3x + 94 + x + 18 + 2x - 4 = 180

Then, we can combine like terms:

6x + 108 = 180

6x = 72

x = 12

We can see that m<COB is the sum of m<COD and m<DOB. We can wrote an equation to model the situation:

m<COB = m<COD + m<DOB

m<COB = x + 18 + 2x - 4

m<COB = 3x + 14

We have the value of x, so we can substitute that in:

<COB = 3(12) + 14

<COB = 36 + 14

<COB = 50°

Firdavs [7]

Answer:

Below.

Step-by-step explanation:

2 3/5 + 8 1/2

= 2 + 8  + 3/5 + 1/2

= 10 + 3/5 + 1/2

The LCM of 5 and 2 is 10 so we get:

10 + 6/10 + 5/10

= 10 + 11/10

= 10 + 1 1/10

= 11 1/10 feet.

P(gray), P(green)


There’s 8 parts…2 gray, 2 green, 1 red, 1 purple, 1 yellow, and 1 blue. So because there’s more gray and green they have the same probability of landing on that color.
