Find <_6 if m <_8 = 120 degrees

IceJOKER [234]

Answer:

120 degrees

Step-by-step explanation:

Since p is parallel to q, <6 and <8 are congruent because of corresponding angles.

m<8=m<6

120=m<6

Since m<8 is 120, and the two angles are congruent, the m<6 is also 120 degrees.

Cancel the common factor of the numerator and the denominator and write specified expression

lisabon 2012 [21]

Step-by-step explanation:

Hello,

I hope you mean to cancel the common factor that exists in numerator and denominator,right.

so, Let's look for the common factor, 

here, the expression is, 

=4(x-2)/ (x+5)(x-2)

so, here we find the common factor is (x-2)

now, we have to cancel it. And after cancelling we get,

=4/(x+5)

Note:{ we cancel the common factor if the common factors are in multiply form.}

Hope it helps

Through: (-5, 5), perp. to y = 5/9x - 4

zysi [14]

Answer:

$y=-\frac{9}{5}x-4$

Step-by-step explanation:

The complete question is:

Find the equation of the line that passes through: (-5, 5), and is perpendicular to the line y = 5/9x - 4

step 1

Find the slope of the line

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

The equation of the given line is

$y=\frac{5}{9}x-4$

The slope of the given line is

$m_1=\frac{5}{9}$

The opposite reciprocal is equal to

$m_2=-\frac{9}{5}$ ----> slope of the perpendicular line

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=-\frac{9}{5}$

$point\ (-5,5)$

substitute

$y-5=-\frac{9}{5}(x+5)$

step 3

Convert to slope intercept form

Isolate the variable y

$y-5=-\frac{9}{5}(x+5)\\\\y-5=-\frac{9}{5}x-9\\\\y=-\frac{9}{5}x-9+5\\\\y=-\frac{9}{5}x-4$
