Answer:
x=35
Step-by-step explanation:
Hello There!
The shown angles are supplementary angles meaning that the sum of the two is 180
so
180=2x+43+2x-3
step 1 combine like terms
2x+2x=4x
43-3=40
now we have
180=4x+40
step 2 subtract 40 from each side
180-40=140
now we have
140=4x
step 3 divide each side by 4
140/4=35
4x/4=x
we're left with
x=35
