Answer:
a = 
b= 4
Step-by-step explanation:
It's a 30-60-90 triangle based on the given picture. A right triangle too
Use sine, cosine, and tangent to solve for the side.
To find b, you can use sin(30) = b/8 because sin(angle) = opposite/hypotenuse.
OR you can use the rule for 30-60-90 triangle, which is x for short leg, 2x for hypotenuse, and
for long leg
So either way, b = 4
To find a, you can use cos(30) = a/8 because cos(angle) = adjacent/hypotenuse.
OR you can use the same rule, 30-60-90 triangle to save time
a will end up = 
Answer:
1
Step-by-step explanation:
the +4 turns into -4
6-4=2 the (+4-4 on the left would cancel out)
-2x/2 would cancel out as well
2 divided by 2 = 1
you could have used a scientific calculator on google (for future reference)
I think h is 658 i could be wrong
Answer:
55 1/2 feet
Step-by-step explanation:
.25 yards = 9 inches
9 inches x 74 bookmarks= 666 inches
12 inches = 1 foot
666 inches/12 inches = 55.5 feet
