The value of X in the figure ABCD witch is a rhombus

Mathematics
1 answer:
NeX [460]2 years ago
5 0

Answer:

  x = 10°

Step-by-step explanation:

The diagonals of a rhombus divide the figure into congruent right triangles. That means the two marked acute angles are complementary.

__

<h3>solve for x</h3>

Complementary angles total 90°, so the relation we can use to find x is ...

  (3x -13) +(8x -7) = 90

  11x = 110 . . . . . . . . . add 20

  x = 10 . . . . . . . . . divide by the coefficient of x

The value of x is 10°.

Write an equation for the line that is parallel to the given line and passes through the given point Y= 1/2 x -8 (-6 ,-17)
mylen [45]
Parallel to : y = 1/2x - 8

Passes through (-6, -17)

Our given slope is 1/2.

Plug the given coordinates into point-slope form.

y - y₁ = m(x - x₁)

y - (-17) = 1/2(x - (-6))

Simplify.

y + 17 = 1/2(x + 6)  ← Your answer.

However, sometimes teachers want this simplified even further.

So, simplify this.

y + 17 = 1/2x + 3

Subtract 17 from both sides.

y = 1/2x + 3 - 17

Simplify.

y = 1/2x - 14 ← Slope-intercept form.

Standard form → -1/2x + y = -14

Tilda makes a scale model of the Titanic. . The actual Titanic was 175 feet tall, Tilda's model is 35 inches tall. What is the s
Greeley [361]

Answer: 1:60

Step-by-step explanation:

Given

The actual titanic is 175 ft tall

Tilda's model is 35 inches tall

first, convert inches into ft

35\ in.\equiv \dfrac{35}{12}\ ft

scale used is

\Rightarrow \dfrac{\dfrac{35}{12}}{175}\\\\\Rightarrow \dfrac{35}{12\times 175}\\\\\Rightarrow \dfrac{1}{12\times 5}=\dfrac{1}{60}

Thus, the scale is 1:60

Answer:

y = 2x - 3

Step-by-step explanation:

Since the equation for the line y = 2x + 5 is already in slope-intercept form (y = mx + b), the slope (m) is 2. A parallel line will have the same slope. Now use point-slope formula to find an equation for the parallel line including point (3,3). Point-slope formula is:  

(y – y₁) = m(x – x₁), where m is the slope (2) and (x₁, y₁) is the point the line passes through (3,3).  

Therefore:  

(y – 3) = 2 (x – 3)

y – 3 = 2x – 6

y – 3 + 3 = 2x – 6 + 3

y = 2x - 3

If a coin has been altered so that the probability of heads coming up is 3/10, then the probability of tails coming up is also 3
Vadim26 [7]
False. Since the probability of one side of the coin is 3/10, the other must be 7/10.
