17x5=85

25x6=150

35x10=350

350+150+85=585

answer=585

Answer:

x = 99°

Step-by-step explanation:

first: find the supplement to 123°:

180 - 123 = 57°

second: since all triangle interior angles total a80°:

180 - 42 - 57 = 81°

third: x = the supplement to 81°, so, x = 180 - 81 = 99°

Answer:

Both are equal to each other.

This answer is correct I got it right on khan.

Step-by-step explanation:

We plot the given vertices (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5) on the graph we get pentagon as shown below.

The given vertices are (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5).

We need to plot the given vertices on the graph.

A point in a plane contains two components where order matters! It comes in the form (x, y) where x comes first, and y comes second.

We plot the given vertices (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5) on the graph we get pentagon as shown below.

The probability that the 12-sided solid gets 3 , 9 or 11 is P ( A ) = 1/4 and the expected number of times is n = 45

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability that the the 12-sided solid gets 3 , 9 or 11 be P ( A )

Now , the value of P ( A ) is

Let the number of outcomes when rolling a 12-sided solid = 12

The number of times the solid is rolled = 180 times

So , the total number of outcomes = 12 x 180 = 2160

And , the probability of getting a 3 = 1/12

The probability of getting a 9 = 1/12

The probability of getting a 11 = 1/12

So , the total probability of getting a 3 , 9 or 11 = 3/12 = 1/4

The total expected number of times = 45

Hence , the probability is 1/6

Answer:

y = 1/4x - 2

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope.

The first line is y = 1/4x. Its slope is 1/4. A line parallel to this one will also have a slope of 1/4.

Plug this value (1/4) into your standard point-slope equation of y = mx + b.

y = 1/4x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (4, -1). Plug in the x and y values into the x and y of the standard equation.

-1 = 1/4(4) + b

To find b, multiply the slope and the input of x (4)

-1 = 1 + b

Now, subtract 1 from both sides to isolate b.

-2 = b

Plug this into your standard equation.

y = 1/4x - 2

This equation is parallel to your given equation (y = 1/4x) and contains point (4, -1)

Answer:

∠1 = 67°

∠2 = 67°

∠3 = 113°

Step-by-step explanation:

∠3 = 113°

∠1 = ∠2

∠1 + ∠2 + ∠3 + 113° = 360°

∠1 = (360 - 113 - 113)/2 = 67°

Answer:

Cos 68

Step-by-step explanation:

Given the expression 2cos² 34° - 1, we are to expression as a single trig ratio.

Let the angle be theta

Recall that sin²theta + cos²theta = 1

sin²theta  = 1 - cos²theta ... 1

also Cos 2theta = Cos²theta - sin²theta  ... 2

Substitute 1 into 2

Cos 2theta = Cos²theta - (1-cos²theta)

Cos 2theta = Cos²theta - 1 + cos²theta

Cos 2theta = 2Cos²theta - 1

Replace theta with 34

Cos 2(34)= 2Cos²(34)- 1

Cos 68 = 2Cos²(34)- 1

Hence the single trig expression is Cos 68
