So far i have.
14) area of sector is πr²/3 = 12π
length of chord. that triangle has two sides of 6 and angle of 120º
split the triangle in two right triangles with angle of 120/2 = 60 and hyp=6. other (longer) side is:
sin 60 = x/6
s = 6 sin 60 = 6(√3/2) = 3√3
third side is
s = 3 cos 60 =...
To start with problem #5 i cut the shape
Into 2, a triangle and a square, i know that the additional leg length to the triangle can be found by subtracting base 1 and base 2=4 so i have a triangle with a hypotenuse of 8 inches, 1 leg=4 and now i have to find the length of the other leg. The...
If i use a2 + b2 = c2
I get 8^+4^=80
80 would be the other leg?
Would this be considered a right triangle?
So one leg would =4 (10-16) and the other 80?
I think the answer to number 1 is 63.0 or 60 if rounded to the nearest tenth, and i think number 2 is. 96.0 or 100 if rounded to the nearest tenth. Need help with 3 and 4. I think for 3 i would add 6 and 8 as the vertical diagonal and the horizontal diagonal would be 5 . 6+8=14 so the area...
