Angle 1 and angle 2 are a linear pair, which make a sum of 180
angle 2=180-angle 1=180-70=110

< 1 + < 2 = 180.....because they form a linear pair and equal 180
70 + < 2 = 180
< 2 = 180 - 70
< 2 = 110 <==

How do I find the area of the shaded region.
vredina [299]

-2x^2 - 32x

Find the area of the entire grey area without the white...

(2x-8)(4x) = 8x^2 - 32x

Find the area of the white...

(5x)(2x) = 10x^2

Subtract the area of the white from the grey...

(8x^2 - 32x) - (10x^2) = -2x^2 - 32x

i solved others lol this isn't right

Prove that angle abc is a right angle with vertices a(-4,3), B(0,-1) and C(2,1)​
spayn [35]

Check the picture below.

clearly the angle at vertex C isn't the right angle, so let's check if AB ⟂ BC.

\bf A(\stackrel{x_1}{-4}~,~\stackrel{y_1}{3})\qquad B(\stackrel{x_2}{0}~,~\stackrel{y_2}{-1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-3}{0-(-4)}\implies \cfrac{-4}{0+4}\implies \cfrac{-4}{4}\implies -1 \\\\[-0.35em] ~\dotfill

\bf B(\stackrel{x_1}{0}~,~\stackrel{y_1}{-1})\qquad C(\stackrel{x_2}{2}~,~\stackrel{y_2}{1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{1-(-1)}{2-0}\implies \cfrac{1+1}{2}\implies \cfrac{2}{2}\implies 1 \\\\[-0.35em] ~\dotfill

\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{-1\implies \cfrac{-1}{1}}\qquad \qquad \qquad \stackrel{reciprocal}{\cfrac{1}{-1}}\qquad \stackrel{negative~reciprocal}{+\cfrac{1}{1}\implies 1}} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{\textit{so is a right triangle}}{AB\perp BC}~\hfill
