What does N equal? N equals -5
Answer:
a = 15/4
Step-by-step explanation:
tan 60 = y/a
√3 = y/a
y = √3a
tan 30 = y/b
1/√3 = y / b
y = b/√3
√3 a = b/√3
3a = b
a+b = 15
a + 3a = 15
4a = 15
a = 15 / 4
Answer:
10 1/12
Step-by-step explanation:
17-6 is 11
11-11/12=
10 1/12
This is the fundamental zero additive rule
x - 0 = x
which means that for the set of real numbers, there exist a number such that if added (or subtracted) from any other will not affect such number.
Answer:
(-5, 2)
Step-by-step explanation:
Three corners of a rectangular city block are located at (2,2), (2,-4) and (-5,-4) on a coordinate plane. What are the coordinates of the fourth Coordinate?
Solution:
A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel. Also, all the angles are at 90 degrees.
Since the city block is rectangular in shape, therefore the fourth coordinate would have the same y coordinate as the point (2, 2) and it would also have the same x coordinate as (-5, -4).
Hence the fourth coordinate is (-5, 2)
