Answer:

Option C: 6x-5y=15

Explanation:

y = -5/6x +8

8 is the <u>y-intercept</u>

-5/6x is the <u>slope</u>

when a slope is in <u>fraction form</u> the numerator is the y direction over the denominator how much the line changes in the x direction

Find cos B exactly if a = 15, b = 11, and angle Cis a right angle
astra-53 [7]

Answer:

Final answer is \cos\left(B\right)=\frac{15}{\sqrt{346}} which is the last choice.

Step-by-step explanation:

In triangle ABC, we have been given a = 15, b = 11, and angle C is a right angle.

Now using those values, we need to find the exact value of cos B.

Apply Pythagorean formula:

AB^2=AC^2+BC^2

AB^2=11^2+15^2

AB^2=121+225

AB^2=346

AB=\sqrt{346}

Now apply formula of cos

\cos\left(B\right)=\frac{BC}{AB}

\cos\left(B\right)=\frac{15}{\sqrt{346}}

Hence final answer is \cos\left(B\right)=\frac{15}{\sqrt{346}}

1. List the properties of a parallelogram
CaHeK987 [17]

9514 1404 393

Answer:

  1. see the list below
  2. no
  3. yes

Step-by-step explanation:

1. The dictionary definition of a parallelogram is ...

  a quadrilateral with opposite sides parallel

As a consequence of this condition, a number of additional properties arise:

  • opposite sides are the same length
  • opposite angles are congruent
  • adjacent angles are supplementary
  • diagonals bisect each other

__

2. The dictionary definition of a trapezoid (US; trapezium, UK) is ...

  a quadrilateral with one pair of parallel sides.

As a consequence of this condition, it is not possible for a trapezoid to be a parallelogram.

__

3. A rhombus is a special case of parallelogram in which all sides are the same length. A square is a special case of rhombus in which all angles are congruent (as are the diagonals). Yes, a rhombus may be a square.
