Answer:
<em> x=17 degrees</em>
<em>m1=97 degrees</em>
Step-by-step explanation:
6x-19=3x+32(vertically opposite angles)
6x-19-3x=32
3x =32+19
3x=51
<em> x=17 degrees</em>
<em />
- when we substitute x in these:
6x-19=83
3x+32=83
if 1=y
83+83+Y+Y=360(points around a point is 360 degrees)
166+2Y =360
2Y =360-166
2Y=194
Y=97
Therefore 1=97 degrees

Answer:
In the figure, by exterior angle property, you have
ACD = A+ B
CBF = A+ C
BAE = B+ C
Adding the above equations, you get
ACD +CBF +BAE = A+ B +A+ C + B+ C
= 2 (A+ B +C)
= 2 180o (angle sum of a )
ACD +CBF +BAE =360o
That is the sum of the exterior angles = four right angles. (360o = 490o)
