Step-by-step explanation:
65+5y=82
5y=82-65
5y=17
y=17/5=3.4
3x+23=54
3x=54-23
3x=31
x=31/3=10.3
5z+43=110
5z=110-43
5z=67
z=67/5=13.4
3x+5y+5z3.
3(3.4)+5(10.3)+5(13.4)
10.2+51.5+67
128.7
Answer:
C
Step-by-step explanation:
I. a // b because m∠2 is on a 180° line, which splits the line into two sections, both being 90°. If m∠1=m∠2, then m∠1 is also 90°. The lines a and b are parallel from each other.
II. since m∠1 is 90°, and for a line to be perpendicular to the other line, they would have to be at a 90°. So, a⊥c because they intersect each other at a 90° angle.
