Basically, the equator is like the x-axis of the world and the prime meridian is like the y-axis. You locate places by distances from these lines.
All angles in a triangle always equal 180 degrees, so to solve this problem you must set 8,3,4 equal to 180. 8x + 3x + 4x = 180. 15x = 180. 180/15 = 12. x = 12. Now you take the value of x and multiply it by the angle you are trying to find. 3(12) = 36.
The measure of the smallest angle is 36.
To check this problem, multiply all the angle ratios by the x value and if it equals 180, it is correct. 8(12) + 3(12) + 4(12) = 180.
So he started with 3/4 lb and ended up with 2/3 of that so 2/3 of 3/4
'of' can be roughly translated as multiply
so 2/3 times 3/4 =6/12=1/2 lb left
or you know that there are 3 out of 4 parts pound left so 2 out of 3 parts of nuts is = 2/4 or 1/2 lb
Does it give you any more details?? if not it would be undefined for parallel and zero for perpendicular.<span />
Let A represent the amount Ann contributed, Z represent Zoe's contribution, and J represent Jim's contribution toward the present.
Ann (A): A
Zoe (Z): A = Z - 12 → Z = 12 + A
Jim (J): A = J - 16 → J = 16 + A
A + Z + J = 154
(A) + (12 + A) + (16 + A) = 154
3A + 28 = 154
3A = 126
A = 42
Ann (A): A = 42
Zoe (Z): Z = 12 + A = 12 + 42 = 54
Jim (J): J = 16 + A = 16 + 42 = 58
Answer: Ann=42, Zoe=54, Jim=58
