Answer: The answer is 39 square feet.

Step-by-step explanation:

By saying square feet it's indicated that you mean the area of this irregular figure.

To do this you can break apart the shape into two pieces.

The first 11 x 3 rectangle then the 2 x 3 rectangle.

Next, you can find the area to be 33 square feet and 6 square feet. respectively, afterward, you add the areas together to find the area of the figure, which is 39 square feet.

Answer:

12.73 Degrees

Step-by-step explanation:

I'm going to assume some things. The height of the truck is not changing, i.e. the the distance and length of the ramp is but the height stays the same.

We draw our right triangle, see photo

We really only care about finding out what side a is so

[tex]c = \frac{a}{ \sin(x) } [/tex]

Note: Let x = A

[tex]12 = \frac{a}{ \sin(36) } [/tex]

[tex]12 \sin(36) = a \\ a = 7.05342302750[/tex]

[tex] \sin(x) = ( \frac{opp}{hyp} ) \\ \sin(x) = ( \frac{7.05342302750}{12} ) \\ = 35.9999 \: degrees[/tex]

So, since I stated that height did not change, same process just using 32 for the hypotenuse.

[tex] \sin(x) = ( \frac{opp}{hyp} ) \\ \sin(x) = ( \frac{7.05342302750}{32} ) \\ = 12.73367164 \: \: degrees[/tex]

Answer:

y-25=180

Step-by-step explanation:

Same line so 180 degrees.

Answer: D or “y + 25 = 180”

a straight line is 180 degrees, therefore the combination of two angles should equal 180.

With that being said the answer should be y plus 25 = 180!

to find y, flip the equation: 180 - 25 = 155. Therefore y = 155 :)

Answer:

g(f(-1)) = 48

Step-by-step explanation:

given the following

f(x) = 5x² + 2

g(x) = x²-1

g(f(x)) = g(5x²+2)

Replace x with 5x² + 2 in g(x) as shown;

g(5x²+2) = (5x²+2))²- 1

g(f(x)) = (5x²+2))²- 1

g(f(-1)) = (5(-1)²+2))²- 1

g(f(-1)) = (5+2))²- 1

g(f(-1)) = (7)²- 1

g(f(-1)) = 49 - 1

g(f(-1)) = 48

Step-by-step explanation:

By inscribed angle theorem

[tex](15x-23)\degree = \frac{1}{2}[360\degree-(91+135)\degree]\\(15x-23)\degree = \frac{1}{2}[360\degree-226\degree]\\(15x-23)\degree = \frac{1}{2}[134\degree]\\(15x-23)\degree = 67\degree\\15x-23 = 67\\15x = 67+23\\15x = 90\\x= \frac{90}{15}\\x=6[/tex]

The term ( 7 - 4 ) is described as a difference or subtraction

An expression is combination of variables, numbers and operators.

The given expression is  5+3(7-4).

Two or more expressions with an Equal sign is called as Equation.

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 5 + 3 ( 7 - 4 )

And , ( 7 - 4 ) is described as a difference or subtraction between 7 and 4.

On simplifying , we get

A = 5 + 3 ( 3 )

A = 5 + 9

A = 14

Therefore , the value of A = 14

Hence , the term ( 7 - 4 ) is described as a difference or subtraction

Answer:

??????????????

Step-by-step explanation:

Answer:

Line 1: zero

Line 2: negative

Line 3: undefined

Line 4: positive

Step-by-step explanation:

Line 1 => slope is horizontal. The slope of horizontal lines are always equal to 0. Therefore, the slope of line 1 is zero.

Line 2 => the line slants downwards form our left to the right, this implies there is a decline or increase. Thus, the slope would be negative.

Line 3 => the line of a vertical line is always undefined. Line 3 slope is therefore undefined.

Line 4 => the slope slants upwards from our left to the right. This indicates a rising slope or an increase. Therefore, the slope of line 4 is positive.

Remark

I take it you are studying the sine law. If that is so, Then it will be set up as

Formula

x/sin(53) = 7 / sin(44)     Multiply both sides by Sin(53)

Solution

Sin(53)x/Sin(53) = 7 sin(53)/Sin(44)

x = 7*Sin(53)/Sin(44)

x = 7 * 0.7986/0.6947

x = 8.0848

Note:

The sine law is always set up by 2 ratios. It consists of the sine of an angle divided by the side opposite = equal to another angle's sine over the side oppose the second angle.

The sine law can also be set up as two ratios side opposite / sin(Angle).
