Answer:
m<SYD = 106.02°. Reason: alternate exterior angles are equal.
Step-by-step explanation:
Y-4= -3(x-3)
First you'll distribute the -3(x-3) and you should get -3x+9 (a negative divided by a negative is a positive)
So your new equation will be y-4=-3x+9. Next you'll get rid of the -4 y adding 4 on both sides of the equation. So you should get y=-3x+13. So points you could use is <span><span>(<span>0,13</span>)</span>,<span>(<span>1,10</span>)</span>,<span>(<span>2,7</span>)</span></span><span />
Similar to the other question, because AB is parallel to CD, you know the 72º angle corresponds to the angle on top of y.
Because that angle above y and y together make a straight line (and a straight line measures 180º), you have
72 + y = 180
Solving that for y, you get y = 108º
