Answer:

x = 78 degrees

Step-by-step explanation:

Let y represent the last angle in the triangle containing 79 degrees and x degrees.

Since the top and bottom lines are parallel, then angle y and angle 23 are alternate angles. Alternate angles are equal. Therefore,

Angle y = 23 degrees

The sum of the angles in a triangle is 180 degrees. It means that

Angle x + angle y + 79 degrees = 180 degrees. Therefore

x + 23 + 79 = 180

x + 102 = 180

Subtracting 102 from the left hand side of the equation and the right hand side of the equation, it becomes

x + 102 - 102 = 180 - 102

x = 78 degrees

The required mixed number is 3\frac{5}{6} . The calculations are attached with the solution as an image.

What is a mixed number ?

  • A bit represented with its quotient and remainder is a mixed bit. For illustration,21/3 is a mixed bit, where 2 is the quotient, 1 is the remainder.
  • So, a mixed bit is a combination of a whole number and a proper bit. A mixed bit, also called a mixed number, is a whole number and a bit together.
  • The bit is written to the right of the whole number.
  • A mixed number is formed by combining three corridor a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper bit that makes the mixed number.

The required mixed number is 3\frac{5}{6} . The calculations are attached with the solution as an image.

Find the slope for the pair of points (1,1)(4,-4)
wolverine [178]
(1, 1) and (4, -4)

Slope formula is : m = (y₂-y₁) / (x₂-x₁)

In this case :

x₁ = 1 ; x₂ = 4 ; y₁ = 1 ; y₂ = -4

Now that you know what variable counts as what, we simply just need to plug everything in.

m = (-4 - 1) / (4 - 1)

Simplify.

m = -5/3

Therefore, your slope is -5/3

If the if a cylinder is 7 in tall and has a volume of 63 Pi inches what is the area of the cross section it goes right down the
vitfil [10]

Answer: 9\pi \ in.^2

Step-by-step explanation:

Given

The height of the cylinder is h=7\ in.

The volume of the cylinder is V=63\pi \ in.^3

The volume of the cylinder is the product of area and height

\Rightarrow V=\pi r^2h\\

Insert the values

\Rightarrow 63\pi =A\times 7\\\\\Rightarrow A=\dfrac{63\pi}{7}\\\\\Rightarrow A=9\pi\ in.^2

Thus, the area of the cross-section is 9\pi \ in.^2
