The rule for clockwise rotation of 90 degrees about the origin is (-y, x).
So (-1,9) would now be (-9,1).
Hope this Helps!!
Angles 1, 3, and 4 make up a straight line.
Thus, 3x + 90 + 3x - 6 = 180 (angle sum of straight line)
6x - 6 = 90
6x = 96
x = 16
Now angle 1 becomes 3(16) = 48
Angle 1, 2, and 3 also make up a straight line.
Thus, angle 2 + 48 + 90 = 180
angle 2 + 138 = 180
angle 2, therefore, becomes 42. In essence, (A)
Answer:
x > 3
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
3x4=12
its 3 because you need to find the balances so when you have 3 and you multiped my 4 you get 12 same as the other square.
This is probably way overcomplicated but i cant remember how to do it
w = n
l = 2n+1
w*l = 66
n(2n+1) = 66
2n^2 + n =66
2n^2 + n - 66 = 0
using quadratic equation
n = 11/2
width = 11/2 = 5.5
length = 11 + 1 = 12
