Answer:

x = (-9)

Step-by-step explanation:

From the diagram, we see that the triangle is an isosceles triangle. Since it is an isosceles triangle we know that the angles at the base of an isosceles triangle are equal to each other, so the angles that is not marked will be equal to m∠2. Since now we know that, we can make the following equation...

m∠2 + m∠2 + 84 = 180

Now we solve it and get...

2(m∠2) = 180 - 84

2(m∠2) = 96

m∠2 = 48

Now we substitute m∠2 with x + 57, and get...

m∠2 = 48

x + 57 = 48

x = 48 - 57

x = (-9)

How much ribbon is required to wrap once around a basketball present? Basketballs are 78 cm in diameter.

Brut [27]

Answer:

C = 78 pi cm

Letting pi = 3.14

C = 244.92 cm

Letting pi = pi button

C = 245.044227 cm

Step-by-step explanation:

We want to find the circumference

C = pi *d

C = pi *78

C = 78 pi cm

Letting pi = 3.14

C = 244.92 cm

Letting pi = pi button

C = 245.044227 cm

At Joe's Grocery, you can buy hot dogs only in packages of 4 or packages of 7. As a result, you can't buy exactly 9 hot dogs sin

Inessa05 [86]

Answer:

Step-by-step explanation:

Hot Dog packages

4 = 2 *2

7 = 1 * 7

To determine, the largest possible number of hot dogs that you can't get exactly by buying these hot dogs is to determine the LCM ( lowest common multiple of 4 and 7 ) and add 1 to it

LCM of 4 and 7 = 1 * 2 * 2 * 7 = 28

Highest number that combining 7 and 4 packages can't give = 28 + 1 = 29
