Answer:
The boat traveled 781.5 feet from point AA to point BB
Step-by-step explanation:
Find the height of the small triangle then find the base of the big triangle then subtract the two answers to find the distance between a and b
:)
45.864, because 57.33 divided by 100 is 0.5733 that multiplied by 80 is 45.864
Answer:
Step-by-step explanation:
BD is opposite the 30° angle. The sine of 30° is 0.5. The sin of an angle in a right triangle is opposite/hypotenuse so BD = sin 30°x8.
Now you have two known lengths The third can be found by applying the Pythagorean theorem: BC²+BD²=CD², from which you can establish a numerical value for BC.
3x-7>2
add 7 to both sides: 3x>9
divide both sides by 3: x>9
Answer:
Step-by-step explanation:
A circumference of a circle can be determined by this: 2*pi*r
We're given the diameter. Divide that by 2 to get the radius.
6.45/2 = 3.225
Now multiply that by 2*pi. That gives us 2 * 3.14 * 3.225 = 20.253.
This could've also been done easier by doing pi*d where d is the diameter and you give the answer by multiplying them both. Also works, but the above formula is just key to many things and can also be used to derive the simpler one. Hope it helps! :)
