find the value of x in the diagram if K and H are compliments.

Answers

Answer 1

Answer:

56°

Step-by-step explanation:

x + 34° = 90° (Complimentary angles)

Answer 2

Answer:

56°

Step-by-step explanation:

Since, angle K and angle H are compliments.

Therefore,

34°+ x = 90°

x = 90° - 34°

x = 56°

Step-by-step explanation:

from a boat on the lake the angle of elevation to the top of a cliff is 18°41’. if the base of the cliff is 991 feet from the boat how high is the cliff (to the nearest foot)

Answers

Answer:

The cliff is 335 feet tall.

Step-by-step explanation:

First you convert the angle to degrees and you get 18.683 degrees.

Then you set up the equation where x is the height of the cliff.

Tan(18.683) = (x/991)

Then you solve for x and you get 335 ft when your ound to the nearest whole number.

The cliff is 355 feet high.

What is Trigonometry?

Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

We have angle of elevation to the top of a cliff is 18°41’.

First, convert the angle to degrees

= 18°41’

= 18.683 degrees.

let x is the height of the cliff.

Using Trigonometry

tan(18.683) = (x/991)

x = 335 ft

write an equation of the line passing through point p(-2,6) that is parallel to the line x=-5

Answers

Answer:

The graph of the line x = -2 is also attached below.

Step-by-step explanation:

Given the line

x=-5

x=-5 represents the vertical. We know that the slope of a vertical line is undefined. Thus, the slope of x=-5 is undefined.

Since parallel lines have the same slopes, it means the line which is supposed to be the parallel line to the given line and passing through p(-2, 6) must also be in the form (x = a).

As the line passes through (-2, 6). As the line is vertical, meaning no matter what the value of y is, the x-value remains the same.

Thus, the equation of the line would be x = -2

(-4,6), slope=-1

Write the slope-intercept equation using the given information.

Answers

Answer:

y = -x +2

Step-by-step explanation:

y = mx + b

y=6

x=-4

m=-1 (m is the slope)

b=? (b is the y-intercept)

Putting these numbers into this equation,

6 = -1(-4) + b

b=6-4

b=2

So the equation is y = -1x + 2

A rectangular field has a length of x metres.
The width of the field is (2x-5) metres.
Show that the perimeter of the field is (6x-10) metres.

Answers

The perimeter of a shape is the length of all the sides added together. In this problem, the length of the rectangle is x and the width is (2x-5). With the information given, we want to show that it equals or is equivalent to (6x-10), which is supposed to represent the perimeter of the rectangle.

Before I write my equation I what to make sure you understand that there are of course two side lengths of this rectangle and two widths. That being said, the equation would look like this:

2x + 2(2x-5) = 6x-10

(both side lengths) + (both widths) = perimeter

I'll show you how you can simplify this equation to show that the perimeter of the field is 6x-10 :

2x + 2(2x-5) = 6x-10

(first step would be to distribute the 2 into 2x-5)

2x + 4x-10 = 6x-10

(add the x's on the left side to simplify)

6x-10 = 6x-10

Well well, what do we have here :). We ended up with the same expression on each side of the equal sign. We totally know that they're equivalent, in fact they're the same.

Answer: Slope: -1/2 y-intercept: 2

Step-by-step explanation:

Subtract 4 x from both sides of the equation. 8 y = 16 − 4 x Divide each term by 8 and simplify. Divide each term in 8 y = 16 − 4 x by 8 . 8 y 8 = 16 8 + − 4 x 8 Cancel the common factor of 8 . Tap for fewer steps... Cancel the common factor. 8 y 8 = 16 8 + − 4 x 8 Divide y by 1 . y = 16 8 + − 4 x 8. y=2−x2. The slope-intercept form is y = m x + b , where m is the slope and b is the y-intercept. y = m x + b Reorder 2 and − x 2 . y = − x 2 + 2. Rewrite in slope-intercept form. y = − 1 2 x + 2.Slope:−1/2 y-intercept:2

Radius r = 4 cm

Length of cylinder = 12 cm

Find:

Volume of solid

Computation:

Volume of solid = Volume of hemisphere + Volume of cylinder

Volume of solid = (2/3)πr³ + πr²h

Volume of solid = (2/3)π(4)³ + π(4)²(12)

Volume of solid = 134 + 603

Volume of solid = 737 cm³ (Approx)

Answer:

737.23

Step-by-step explanation:

formua for sphere:

V = 4/3 πr^3

so the volume would be 268.08

divide by 2 bc its only half of a sphere

you get 134.04

formula for cylinder:

V = πr^2h

so the vlume would be 603.19

add the volumes together you get 737.23
