The first two angles in a triangle are 100 degrees and 70 degrees. What does the third angle have to be?

A. 1 Degrees
B. 10 Degrees
C. 100 Degrees
D. 180 Degrees

Answer:

Solution given:

sin y = -4/5

p/h=4/5

p=4

h=5

b=√{5²-4²)=3

cos y = b/h=-3/5

again

cos x=12/13

b/h=12/13

b=12

h=13

p=√(13²-12²)=5

sin x=p/h=5/13

now

sin[x-y]=sinxcosy-cosxsiny

=5/13×-3/5-(12/13×-4/5)=33/65 is your answer.

Complete question :

Gary has (20x + 7) dollars. Gary decides to buy two pairs of jeans. Each pair of jeans costs (2x - 3) dollars. write an expression that represents how much money gary will have left over after the purchase then simplify your expression

Answer:

$(16x - 1)

Step-by-step explanation:

Given that:

Amount Gary has = $(20x + 7)

Price per pair of jeans = $(2x - 3)

Number of pairs = 2

Cost of 2 Jean pairs = 2 * $(2x - 3) = $(4x - 6)

Amount left after purchase :

$(20x - 7) - $(4x - 6)

20x - 7 - 4x + 6

20x - 4x - 7 + 6

$(16x - 1)

Answer:

standard form for a quadratic expression

Step-by-step explanation:

This is a quadratic expression.  If you want this expression in standard form, write the terms in descending order of powers of x:  -2x^2 + 1.

This   -2x^2 + 1   has not yet been factored.

-2x^2 + 1 is in standard form.

Answer:

105°

Step-by-step explanation:

<2 and <6 are corresponding angles and have equal measure.

Now

<1+<2=180°

<1=180°-<2

<1=180°-75°=105°

Answer:

5 rooms

Step-by-step explanation:

4 rooms = 9 hours

9 hours = 540 minutes

1 room = 540 ÷ 4 = 135 minutes

60 x 12 = 720 minutes (12 hours)

720 ÷ 135 = 5.33333

5.3333 estimated to nearest whole number = 5

Answer: 118846.973684 = 118847.0cm^3 it not 1.1 or 1.2

\

The volume of a sphere with a radius of 30.5 cm is, 118,786.72 cm³.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

The radius of sphere = 30.5 cm

Now, We know that;

The volume of sphere = 4/3πr³

Where, 'r' is radius of sphere.

Hence, We get;

The volume of sphere = 4/3πr³

The volume of sphere = 4/3 × 3.14 × (30.5)³

The volume of sphere = 118,786.72 cm³

Thus, The volume of a sphere with a radius of 30.5 cm is, 118,786.72 cm³.

Answer:

A.......No, the distance from the restaurant to Ada’s house is  miles, which is greater than the 6-mile maximum radius

Step-by-step explanation:

Using the distance between two points, it is found that the correct option regarding whether Ada’s house lie on or within the circle representing the area that gets free delivery is given by:

a. No, the distance from the restaurant to Ada’s house is [tex]\sqrt{41}[/tex] miles, which is greater than the 6-mile maximum radius.

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

In this problem, we want to find the distance between the restaurant at the origin (0,0) and Ada's house at point (-4,5), hence:

[tex]d = \sqrt{(5 - 0)^2 + (-4 - 0)^2} = \sqrt{41} > 6[/tex]

Greater than 6 miles, hence option a is correct.

Answer: 34 books

Step-by-step explanation:

Since Erik read a total of 4 books over 2 months. This means that every month, he read (4/2) = 2 books.

After belonging to the book club for 17 months, the number of books that he'll have read will be the number of books he read per month multiplied by 17 months. This will be:

= 2 × 17
