Finding side length of the 90-degree angle triangle

Mathematics
1 answer:
allsm [11]3 years ago
8 0

Answer:

x = 4

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = \frac{1}{\sqrt{2} }

sin45° = \frac{opposite}{hypotenuse} = \frac{x}{4\sqrt{2} } = \frac{1}{\sqrt{2} } ( cross- multiply )

\sqrt{2} x = 4\sqrt{2} ( divide both sides by \sqrt{2} )

x = 4

Answer:  D) 6

Focus on the second equation given. The period of that equation is simply the value of b. Because b = 6, this means the period is 6. The function repeats itself every 6 units; in other words, the length of a full cycle is 6 units.

Solve the following 3 × 3 system. Enter the coordinates of the solution below.

Answer:

  (x, y, z) = (-1, 0, -3)

Step-by-step explanation:

We notice that the coefficients of z are such that elimination of the z term from the equations is made easy.

Adding equations 1 and 2:

  (2x -3y -2z) +(x +3y +2z) = (4) +(-7)

  3x = -3

  x = -1

Adding equations 2 and 3:

  (x +3y +2z) +(-4x -4y -2z) = (-7) +(10)

  -3x -y = 3

Substituting for x, we get ...

  (-3)(-1) -y = 3

 0 = y . . . . . . . . . . . add y-3 to both sides

Then z can be found from any equation. Substituting for x and y in the second equation gives ...

  -1 +2z = -7

  2z = -6 . . . . . add 1

  z = -3 . . . . . .divide by 2

The solution is (x, y, z) = (-1, 0, -3).
