Let the measure of bcd = aº. because bcd and bad form a circle, and a circle measures 360°, the measure of bad is 360 - aº.
because of the _ _theorem, m za- degrees and m2c = 360 - a degrees. the sum of the measures of angles a
and c is + 360- degrees, which is equal to 360° or 180°. therefore, angles a and c are supplementary because their
measures add up to 180° angles b and d are supplementary because the sum of the measures of the angles in a quadrilateral
is 360° m 2a + m2c + m 2b + m2d = 360°, and using substitution, 180° + m 2b + m 2d = 360°, som zb + m 2d = 180°
what is the missing information in the paragraph proof?

y=mx+b is the final answer!   : )

a 360 degree rotation

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

i don't see any
