how do I solve it in slope intercept for so that it's perpendicular to the given line and that passes through the given point

Y = -3x + 4 this line has slope = -3

perpendicular lines, slope is opposite and reciprocal
so slope of perpendicular line is 1/3

passing thru (6,-2)
y = mx + b
b = y - mx
b = -2 - (1/3)(6)
b = -2 - 2
b = -4

equation
y = 1/3(x) - 4

hope it helps

Answer:

just do this and you will find you anwer

Step-by-step explanation:

Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

Answer:

Step-by-step explanation:

<u>Law Of Cosines:</u>

$cos(A)=\frac{b^2+c^2-a^2}{2bc}$

This should work for any side. This can generally be thought as:

$cos(\text{angle}) = \frac{\text{sum of squares of two other sides-opposite side squared}}{\text{2 times the product of the other two sides}}$

If this is too confusing here's the formula for the other sides (which is essentially the same, just different variables)

$cos(B)=\frac{a^2+c^2-b^2}{2ac}$

$cos(C) =\frac{a^2+b^2-c^2}{2ab}$

Anyways now just plug in the known values into the equation

$cos(A)=\frac{4^2+6^2-3^2}{2(6)(4)}\\$

Square and multiply values

$cos(A)=\frac{16+36-9}{48}$

Add the values in the numerator

$cos(A)=\frac{43}{48}$

Take the inverse of cosine on both sides

$A=cos^{-1}(\frac{43}{48})$

calculate arccosine (inverse cosine) using a calculator

$A\approx 26.384$

Round to nearest tenth

$A\approx26.4$

Answer:

obtuse, scalene

Step-by-step explanation:

1 obtuse angle makes the triangle obtuse all sides are different so it would be a scalene triangle

Answer:

x = 2, y = 5

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, thus

PT = TR and QT = TS

Substitute in values

y = 2x + 1 → (1)

3y = 3x + 9 → (2)

Substitute y = 2x + 1 into (2)

3(2x + 1) = 3x + 9

6x + 3 = 3x + 9 ( subtract 3x from both sides )

3x + 3 = 9 ( subtract 3 from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

Substitute x = 2 into (1)

y = 2(2) + 1 = 4 + 1 = 5

An angle measures 6 times the measure of its supplemantary angle. Find the measure of both angles

galben [10]

Answer:

<em>180/7 deg and 1080/7 deg</em>

Step-by-step explanation:

The measures of two supplementary angles add to 180 degrees.

One angle measures x.

The supplement measures 6x.

The sum of the measures is 180 deg.

x + 6x = 180

7x = 180

x = 180/7

6x = 1080/7
