Answer:

67 degrees

Step-by-step explanation:

If angle a is 113 degrees, angle d will be 113 degrees subtracted from 180 degrees. Because angles in a straight line adds up to 180 degrees.

X varies directly with y. If x is 16 when y is 20, find x when y is 80.

Taya2010 [7]

Answer:

Step-by-step explanation:

16/20 reduces down to 2/5

set 2/5=x/80

cross multiply 160=5x

divide 32=x

check 2/5=32/80

32/80; 16/40; 8/20; 4/10; 2/5

yay 32 is the answer good luck :)

What are the excluded values for m+4m+2=8m+2?

aliina [53]

That equation is the same as 3m=0, only m=0 works. Do you think they want you to say, all numbers but zero are excluded? Or is the equation different?

Find the equation of the line that passes through the point left-parenthesis 1 comma 8 right-parenthesis and is perpendicular to

Furkat [3]

Don't be shy about using actual parentheses and commas.

Line through (1,8) perpendicular to

$-\dfrac 4 5 x + \dfrac 5 4 y = -4$

The perpendicular family is gotten by swapping the coefficients on x and y, negating exactly one of them. The constant is given directly by the point we're through:

$\dfrac 5 4 x + \dfrac 4 5 y = \dfrac 5 4 (1) + \dfrac 4 5 (8) = \dfrac 5 4 + \dfrac{32}{5}$

Let's clear the fractions by multiplying both sides by 20.

$25x + 16y = 25 + 128 = 153$

Might as well stop here.

Answer: 25 x + 16 y = 153
