The ladder, floor and wall form a straight triangle. The angle between floor and wall is obviously 90, between floor and ladder is 38 (given), so the angle between wall and ladder must be (180-90-38 = 52).
The law of sines says that the side length divided by the sine of the opposite corner is a constant for all three corners.
Let's say the floor length is f.
Then 70/sin(38) = f/sin(52), so f = 70*sin(52)/sin(38) ≈ 89.6.
13-x = 13- x
theres is no answer for that x its a variable and 13 is a constant so is just 13-x
Answer:
For a glider, which a paper airplane is the more lift the glider has the longer it can fly. However, you must keep the weight and drag in check to avoid flight failure.
Step-by-step explanation:
Answer:
n = 98
Step-by-step explanation:
8/11 x (n - 10) = 64
multiply both sides of the equation by 11/8
11/8 x 8/11 x (n-10) = 11/8 x 64
reduce the numbers with greatest common divisor 11
1/8 x 8 (n-10) = 11/8 x 64
n - 10 = 11 x 8
multiply the numbers
n - 10 = 88
so then you add the numbers
n = 88 + 10
n= 98
