Answer:
y = root under 24 (evaluate it if necessary)
or y = 2 root 6
Step-by-step explanation:
Let the reference angle be x
for the triangle in left,
b = 6-4 = 2
Now,
taking x as refrence angle,
cosx = b/h
or, cosx = 2/h
again,
for the bigger triangle,
taking x as reference angle,
cosx = b/h
or, cosx = b/6
As we can see base of bigger triangle is equal to hypotenuse of triangle at the left,
Let's suppose its a
so, cosx = a/6 = 2/a
now,
a/6 = 2/a
or, a² = 12
now,
for bigger triangle, using pythagoras theorem,
h² = p²+b²
or, 6² = y² + a²
or, 36 = y² + 12
or, y² = 24
so, y = root under 24
Answer:
fraction:1/6 decimal:0.166666 repeated percent:16.6 repeated
Step-by-step explanation:
8 gallons= 128 cups
20 guests x 2 cups each= 40 cups will be gone
128-40= 88 cups left over
88 cups= 5.5 gallons of punch left at the end of the party.
2,000 is 10 times as much as 200. To find the answer we can divide 2,000 by 10:
2,000 / 10 = 200
It means that 200 is also 1/10 of 2,000.
If you want to find out what 2,000 is 1/10 of, then just multiply it by 10:
2,000 * 10 = 20,000
2,000 is 1/10 of 20,000.
