Answer:
Find out all the other angles, and add them together. Subtract 180 - all the other angles combined.
BOOM, you found x for the interior angles.
Answer: At point (
)
Step-by-step explanation: <u>Diagonal</u> is a line uniting two opposite points. In a square, the diagonals intersect in a 90° and bisect each other, i.e., divides each diagonal into two segments of the same length.
In other words, the diagonals of a square meet at their midpoint, which is found as the following:
(x,y) = 
The opposite vertices of the given square are (-2,6) and (1,-7).
So, the intersection is
(x,y) = 
(x,y) = 
The diagonals of square with vertices (-2,6)(6,1)(1,-7)(-7,-2) intersect at point

1/9 of the aquarium was filled with 1/7 liter
1 whole fraction of the aquarium will be filled = 1/7 ÷ 1/9
= 1/7 * 9/1 = 9/7
9/7 liters or 1 2/7 liters will be needed.
It’s a square or a parallel
Answer:
The equation of the line normal to the curve of y=cos1/3x, where x=pi is y= 2√3 x - 10.38
Step-by-step explanation:
The equation of the normal to the curve is
Y- y1 = - 1/m (x- x1)
Where m is the gradient.
