Answer:
Step-by-step explanation:
It is asking you what you would put as your statement for step 4.
The answer by the way would be what you have clicked on - angle 1 + angle 4 = 180 degrees.
(3x+5)+(x+3)=180
4x+8=180
4x=172
x=43
3(43)+5
<PQR=134
<SQR=46
39.5
angle ABC=60=(5x+2)+(3x-2)
60=8x
x=7.5
Angle ABD=(5x+2),(sub x=7.5)
=(5*7.5+2)
=39.5
