Answer:
D. Lines coincide
Step-by-step explanation:
On dividing y/2y and 4/8 and x/2x you get 1/2. Since 1/2 is common answer for all the parts, lines will coincide.
If using the radius, you would multiply the radius by 2*pi, to calculate the circumference, which should be the same as the answer i got.
-4=-1b-(1/3)b
-4=-(4/3)b
-4/-(4/3)=b
b=3
-------------------------------
(1/2)3+(5/3)2
3/6+10/6=13/6
-23/3=13/6a
(-23/3)/(13/6)=a
a=-46/13
Answer:
11.4 units
Step-by-step explanation:
a/sinA = b/sinB
17/sin(88) = b/sin(42)
b = sin(42) × 17/sin(88)
b = 11.3821540088
