Look at the picture.

1 unit right (+1); 2 units down (-2)

A(1, 3) → A'(1+1, 3-2) → A'(2, 1)

B(4, 5) → B'(4+1, 5-2) → B'(5, 3)

C(3, 1) → C'(3+1, 1-2) → C'(4, -1)

(x, y) → (x + 1, y - 2)

If the measure of angle 2 is 92 degrees and the measure of angle 4 is (one-half x) degrees, what is the value of x?

zavuch27 [327]

Answer: x = 184°

Step-by-step explanation: As we can see in the figure below, angles 2 and 4 are Vertical Angles, i.e., they are angles opposite each other when two lines cross. Vertical angles are always congruent.

Then,

m∠2 = m∠4

$92=x.(\frac{1}{2})$

$92=\frac{x}{2}$

Value of x is

$x=92(2)$

x = 184

The value of x is 184°.

Find the value of the trigonometric ratio: tan X.

serious [3.7K]

Answer:

The value of the trigonometric-ratio:

Tan X = 24 / 7

Step-by-step explanation:

Given the angle X

It is clear that:

The opposite of the angle X = 48

The adjacent to the angle X = 14

We know that the trigonometric-ratio of Tan X is defined as

Tan X = Opposite / Adjacent

substituting Opposite = 48, and Adjacent = 14

Tan X = 48/14

Tan X = 24 / 7

Therefore, the value of the trigonometric-ratio:

Tan X = 24 / 7

Answer:

RS = √(b² +(c -a)²)

Step-by-step explanation:

Put the given point coordinates in the given formula:

R = (x₁, y₁) = (0, a)
S = (x₂, y₂) = (b, c)

RS = √((b -0)² +(c -a)²)

RS = √(b² +(c -a)²)

The length of a rectangle is 8 m more than 6 times the width. The perimeter is 156 m. Find width.

Alla [95]

width = x
length = 6x + 8

x + 6x + 8 = 156/2
7x + 8 = 78
7x = 78 - 8
7x = 70
x = 70/7
x = 10 m ← width
