<4= 164
Step-by-step explanation:
the sum of any 2 angles of a triangle is equal to the exterior linear angle of the triangle
<1+<2=<4
8x+9+5x+12=14x+10
13x+21=14x+10
21=x+10
11=x
<4=14x+10
<4=14(11)+10
<4=154+10
(<em>x</em>, <em>y</em>) represent coordinates, <em>m</em> represents slope, and <em>b</em> represents the y-intercept
