The right answer for the question that is being asked and shown above is that:

This can be answered using the Pythagorean Theorem.
h2 = a2 + b2
h = square root (10^2 + 7^2)
h = <span>square root (100 + 49)
h = </span><span>square root (149) cm

So the correct answer is </span>h = <span>square root (149) cm</span>

Answer:

  y = -3x -4

Step-by-step explanation:

A perpendicular line has a slope that is the negative reciprocal of that of the given line. When the equation starts out in standard form, a line with negative reciprocal slope can be written by swapping the x- and y-coefficients and negating one of them.

The given x- and y-coefficients have the ratio 1:-3, so we can use the coefficients 3 and 1 for our purpose.

The usual process of making the line go through a given point can be used. That is, we can translate the line from the origin to the desired point by subtracting the point coordinates from x and y. Then we have ...

  3(x+3) +(y-5) = 0

__

This is "an" equation. It is in no particularly recognizable form. It can be rearranged to the form y = mx + b:

  3x +9 +y -5 = 0 . . . . . eliminate parentheses

  y = -3x -4 . . . . . subtract terms that are not "y"

Solve for h<br> h - 3h - 8 = 14<br> H=?
sweet [91]

The initial step that must be taken before solving almost any problem is to understand what the problem is asking for us to do and what is provided to us to complete that goal.  Looking at the problem statement, we can see that we are being requested to solve for h and we are provided an expression to do so.  Let's begin solving the expression by combining like terms.

<u>Combine like terms</u>

  • h - 3h - 8 = 14
  • (h - 3h) - 8 = 14
  • (- 2h) - 8 = 14

Just a quick explanation on what combine like terms means, it basically just means to combine the coefficients of the numbers associated with the same variables.  Like in this example we can combine h and -3h because they have have the variable h associated with them.

<u>Add 8 to both sides</u>

  • (- 2h) - 8 = 14
  • (- 2h) - 8+ 8 = 14 + 8
  • - 2h= 22

<u>Divide both sides by -2</u>

  • - 2h= 22
  • \frac{- 2h}{-2}= \frac{22}{-2}
  • h= \frac{22}{-2}

<u>Simplify the expression</u>

  • h= - \frac{22/2}{2/2}
  • h= - \frac{11}{1}
  • h= - 11

Therefore, after completing the steps above we were able to determine that the value of h is equal to -11.

In ΔABC , angle C is a right angle.
guajiro [1.7K]

Answer:  Choice A. sin(A) = cos(B)

============================================================

Explanation:

The rule is that sin(A) = cos(B) if and only if A+B = 90.

Note how

  • sin(A) = opposite/hypotenuse = BC/AB
  • cos(B) = adjacent/hypotenuse = BC/AB

Since both result in the same fraction BC/AB, this helps us see why sin(A) = cos(B). Similarly, we can find that cos(A) = sin(B).

In the diagram below, the angles A and B are complementary, meaning they add to 90 degrees. So this trick only applies to right triangles.

The side lengths can be anything you want, as long as you're dealing with a right triangle.
