First solution:
Second solution:
Hence, we have that the correct option is the second option:
Have a nice day!
Answer:
6/4y - 12 = 1/2y -4
3/2y -12 = 1/2y - 4
-1/2y -1/2y
2/2y - 12 = -4 (2/2 = 1)
y - 12 = -4
+12 +12
y = 8
Step-by-step explanation:
A = L * W
W = 8
L = 4W....L = 4(8) = 32
A = 32 * 8
A = 256 m^2 <==
The answer is 6.33 units.
Step One
Find z
All triangles have 180 degrees. No exceptions.
z + 47 + 90 = 180 combine like terms on the left.
z + 137 = 180 subtract 137 from both sides
z = 180 - 137
z = 43 degrees.
Step Two
Use the sine function to find y
Sin(43) = opposite side / hypotenuse
opposite side = 35
sin(43) = 35 / hypotenuse
hypotenuse = 35 / sin(43)
y = 35/0.6820
y = 51.32
Solve using cos(x)
Note this problem could have been done in a shorter way.
Cos(47) = adjacent / hypotenuse.
hypotenuse = adjacent / cos(47)
y = 35 / cos(47)
y = 35 / 0.6820
y = 51.32 Both answers agree. It is a good thing to know how to do this question both ways.
