5. Find The Measure Of The Missing Angle.40

Answers

Answer 1

50°

Step-by-step explanation:

40° + 90° + ? = 180°

130° + ? = 180°

? = 180° - 130°

? = 50°

Answer 2

Answer: 50 degrees

Step-by-step explanation: The interior angles add up to 180.

1. 40 + 90 + ? = 180

     130 + ? = 180

   -130         - 130

            ? = 50

we first substitute the x

y= -2(-2-1)

=6

and then use a calculator to do the sum

which gives us 6

y= -2(-1-1)

= 4

Step-by-step explanation:

sin^2 x - 2sinx + 2 = sin^2 3x

Answers

Recall the triple angle identity for sine:

sin(3x) = 3 sin(x) cos²(x) - sin³(x)

… = 3 sin(x) (1 - sin²(x)) - sin³(x)

… = 3 sin(x) - 4 sin³(x)

So the equation is equivalent to

sin²(x) - 2 sin(x) + 2 = sin²(3x)

sin²(x) - 2 sin(x) + 2 = (3 sin(x) - 4 sin³(x))²

sin²(x) - 2 sin(x) + 2 = 9 sin²(x) - 24 sin⁴(x) + 16 sin⁶(x)

16 sin⁶(x) - 24 sin⁴(x) + 8 sin²(x) + 2 sin(x) - 2 = 0

or, by replacing y = sin(x),

16y ⁶ - 24y ⁴ + 8y ² + 2y - 2 = 0

By inspection, y = 1 is a root, since

16 - 24 + 8 + 2 - 2 = 0

so we get one family of solutions,

sin(x) = 1   ===>   x = arcsin(1) + 2nπ = π/2 + 2nπ

Now suppose y ≠ 1. Dividing both sides of the sextic equation by y - 1 then gives

(16y ⁶ - 24y ⁴ + 8y ² + 2y - 2)/(y - 1) = 0

16y ⁵ + 16y ⁴ - 8y ³ - 8y ² + 2 = 0

Unfortunately, the remaining roots can only be obtained through numerical methods. Using a calculator, you would find

y ≈ -1.127

y ≈ -0.475 ± 0.368i

y ≈ 0.539 ± 0.127i

But if you're solving over the reals, you can ignore these solutions. Remember that sin(x) is bounded between -1 and 1, and its value goes outside this interval only when x is complex.

17+32=49

32+49=81

49+81=130

81+130=211

Answer:

130 and 211

Step-by-step explanation:

15,17,32,49,81 _ _

15+2=17+15=32+17=49+32=81

1) make q the subject of the formula 4(q+p)=5+7q

1) [tex]q = \frac{4p}{3} -\frac{5}{3}[/tex]

2) [tex]x = \frac{\sqrt{b -y + 2a} }{b}[/tex]

Step-by-step explanation:

1) 4(q + p) = 5 + 7q

  Multiply 4(q + p):

  4q + 4p = 5 + 7q

  4p - 5 = 7q - 4q

  4p - 5 = 3q

  [tex]\frac{4p}{3} - \frac{5}{3} = \frac{3q}{3}[/tex]

Answers

Answer:

the answer is 21.8

Substitute the value of the variable into the equation and simplify.

If x is 1.9 then the equation turns into: 2(1.9+9) so

1.9+9 = 10.9. Then since it was parentheses it will go back to: 2(10.9). If any number is in parentheses and doesn’t have a plus or minus sign in-front of it, then you multiply, So 2 times 10.9= 21.8.

Thus, If x= 1.9, Then 2(x+9)= 21.8.

A water tank in Stewart's

Loss of 1 3/5 mL in 10 min.
a. Use a complex fraction to
represent the change in the
volume of water in 1 minute.
___ milliliters
10 minutes
b. Simplify the complex fraction to find the change in the volume of water in the tank in 1 minute.

Answers

The change in the volume of water in 1 minute is a decrease of 0.16 milliliters.

Since a water tank in Stewart's home had a small, steady leak loss of 1 3/5 mL in 10 min, to find the change in the volume of water in 1 minute, the following calculation must be performed:

The total leak must be calculated and divided by the 10 minutes duration.  3/5 = 0.6 1 + 0.6 = 1.6 1.6 / 10 = 0.16

Therefore, the change in the volume of water in 1 minute is a decrease of 0.16 milliliters.

At a pet store the ratio of cats to dogs sold was 6 : 5. If there were 12 cats that were sold, how many dogs were sold?

Answers

Ratio of cats to dogs is 6:5.

Which means for every 6 cats sold 5 dogs are sold.

Is 12 cats are sold: 6*2=12
Because we multiply the number of cats sold by 2 we do the same for dogs:
5*2=10.

So, if 12 cats are sold then 10 dogs are sold.
The answer is 10.

What is a triangle?

The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

As per the given information in the question,

Use the equation of Pythagoras' theorem,

h² = p² + b²

(2x - 2)² = x² + (x - 2)²

4x² - 2(2x)(2) + 4 = x² + x² + 4 + 4x

4x² - 8x + 4 = 2x² + 4x + 4

4x² - 2x² - 8x - 4x + 4 - 4 = 0

2x² - 12x = 0

2x² - 12x = 0

2x(x - 6) = 0

So,

2x = 0

⇒ x = 0, it is not possible.

Or,

x - 6 = 0

x = 6
