The measure of each angle is 159° and 21°.

<h3>What are supplementary angles?</h3>
  • When two straight lines or rays intersect at a single endpoint, an angle is created.
  • The vertex of an angle is the location where two points come together.
  • The Latin word "angulus," which means "corner," is where the word "angle" originates.
  • Two angles are considered to be supplementary if their sums total 180 degrees.
  • For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.

So, supplementary angles = 180

Then,

  • 2x + 138 = 180
  • 2x = 180 - 138
  • 2x = 42
  • x = 21
  • 21 + 138 = 159

Therefore, the measure of each angle is 159° and 21°.

Answer:

arc EFC = 237°

Step-by-step explanation:

arc DEF = 140°

arc EF = 140° - 83° = 57°

arc DC = arc FG

arc DC = (360° - 140° - 140°)/2 = 40°

arc EFC = arc CG + arc FG = arc EF = 140° + 40° + 57° = 237°

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible c
lutik1710 [3]

Answer:

Tamara should expect the sum of the two cubes to be equal to 5 20 times.

Step-by-step explanation:

The sample space of rolling a number cube are:

S = {1, 2, 3, 4, 5, 6}

If two such cubes are rolled together, then the sum of the two cubes will be 5 for the combinations below:

S₁ = {(1, 4), (2, 3), (3, 2) and (4, 1)}

The total number of outcomes will be, <em>N</em> = 36.

Compute the probability that the sum of rolling two numbered cubes as follows:

P(\text{Sum}=5)=\frac{4}{36}=\frac{1}{9}

Let <em>X</em> = number of time the sum of the two numbers on two cubes is 5.

Two numbered cubes are rolled <em>n</em> = 180 times.

The event of getting a sum of 5 in independent of the other results.

The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 180 and <em>p</em> = \frac{1}{9}.

The expected value of <em>X</em> is:

E(X)=np

Compute the expected number of times Tamara expects the sum of the two cubes to be equal to 5 as follow:

E(X)=np\\=180\times \frac{1}{9}\\=20

Thus, Tamara should expect the sum of the two cubes to be equal to 5 20 times.

Evaluate ab for a = -2 3/4 and b= - 4/6
nataly862011 [7]

Answer:

1  5/6

Step-by-step explanation:

ab = (-2 3/4) * (-4/6)

     = ( -11/4) * ( -4/6)

     = (11 * 4) / (4 * 6 )

      = 11/6

       = 1  5/6

681/4 i dont know this
ankoles [38]

Answer:

170.25

Step-by-step explanation:

It's a bit tricky to do not on plain paper, but here:

Just assume the long division symbol looks right

  _1_7_0_.25

4 ) 681

    -4

     2 8

     -2 8

          0  1

The remainder is "1", so you'll just have to write that as either a fraction or decimal, whatever is assigned.

Fraction: 170 1/4

Decimal: 170.25
