Answer:In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle. Explicitly, a first line is perpendicular to a second line if (1) the two lines meet; and (2) at the point of intersection the straight angle on one side of the first line is cut by the second line into two congruent angles.
Step-by-step explanation:
Answer:
8/3
Step-by-step explanation:
Because all 4 angles are congruent, the sides are proportional.
the scale factor is 5/30 = 1/6.
meaning x = 16(1/6)=8/3.
Answer:
The values are given below.
Step-by-step explanation:
Mrs. Jackson bakes cookies for her family and colleagues at work. The number of cookies she bakes on the x-th day of December is given by,
f(x) = 
until 24-th of December.
So, we can construct the following table,
x f(x)
0 24
4 20
8 16
12 12
16 8
20 4
24 0

Triangle angles add to 180 degrees. Thus, x - 17, x - 22, and 3x + 19 add to 180.
Add like terms to get 5x - 20 = 180
5x = 200
x = 40
