Answer:
z =15cm and
y=9.0cm
Step-by-step explanation:
Use sine rule
12/ sin53 = z / sin 90
Z = 12 x sin 90 / sin 53
Z = 15cm
To find y the angle opposite to y will be 180-(90+53)=37º
So
15/sin 90= y/sin37
y= 15 x sin37 /sin 90
y = 9.0cm
What is the question?
-20 = 0
-8 (6 + x) + 4 (2x + 7) = 0
-48 - 8x + 8x + 28 = 0
26 mph
d/t = r (distance/ time = rate)
104/4 = 26
