Answer:
Use a protractor
Step-by-step explanation:
Im still working on it give me a sec.
Step-by-step explanation:
since I don't have any data about the coordinates, I am simply calling them xj, yj, and xj' and yj'.
J = (xj, yj)
K = (xk, yk)
L = = (xl, yl)
a translation (shift) 2 units to the left just means, that the y coordinates regain the same, but the x coordinates are decreased ("to the left" = getting smaller) by 2.
J' = (xj - 2, yj)
K' = (xk - 2, yk)
L' = (xl - 2, yl)
Answer:
x = ±2
Step-by-step explanation:
9x^2-36=0
Using the square root property
9x^2 = 36
Divide each side by 9
x^2 = 4
Take the square root of each side
sqrt(x^2) = sqrt(4)
x = ±2
It would be the 2nd object or letter B
Step-by-step explanation:
We are going to start by working out the interior angles so first of all to work out the interior angle we used the formula: num of sides - 2 * 180 for the sum of degrees in a shape.
Lets test this formula.
Lets say we have a square it has 4 sides 4-2 = 2 *180 = 360 this is correct,meaning we can trust this formula.
Now lets put it to use.
Octagon has 8 sides - 2 = 6.
6 * 180 = 1080
Pentagon has 5 sides - 2 = 3
3 * 180 = 540
Another Pentagon 5 sides - 2 = 3
3 * 180 = 540
We have to find out a single angle because it is one side that joins to the other, also if it is a perfect fit then all the single angles must add up to 360.
1080/8 sides = 135 degrees
540 / 5 sides = 108 degrees
540 / 5 sides = 108 degrees
We add these up,
135 + 108 + 108 = 351 which cannot be a possible fit because we need 360 degrees.
Hope this helps
