Answer:50%
Step-by-step explanation:
Answer:
81°+x=180°[co interior angles]
x=180°-81°
x=99°
x°=(3y+33)°
99°=(3y+33)°
99-33=3y
66=3y
66/3=y
22=y
Answer:
I belevie its 4
Step-by-step explanation:
<span>points (6,10)
</span>y = -x
x + y = 0
distance = lax1 + by1 + cl/√(a^2 + b^2)
= l1(6) + 1(10) + 0l/√(1^2 + 1^2)
= l6 + 10 + 0l/√(1 + 1)
= l16l/√2
= 16/√2
= 8 .2/√2
= 8 . √2.√2/√2
= 8√2
