Answer:
The length of a rectangle is 2 feet more than it's width. How do you find the dimensions of the rectangle if its area is 63 square feet?
Step-by-step explanation:
x(x+2) = 63
x^2 + 2x = 63
x^2 + 2x - 63 = 0
Quadratic formula with numbers plugged in: (-2 +or- sqrt(4 - 4* 1 * -63))/2 becomes
-2 +or- sqrt(256)/2 so (-2 +or- 16)/2 therefore -18/2 or 14/2. Discard negative result.
x = 7. 63/7=9. Sides are 7ft and 9ft.
Answer:
The same as the angle for K
Focus on the left side and imagine you ride a motorcycle on the dotted path.
in both left corners you turn around 180° with exactly two rather sharp turns.
We already know that one is 65°, so the other one has to be 115°.
Hence, the angles of K and L are 115°
