angle B& C = 180
C & D = 180
A & D = 180
A & B = 180
A & C are identical so angle x = 63
angle Z = mirrored angle which is 72
180-63 = 117-72 = 45
so angle y = 45
Answer:
There are many ways to interpret if whether or not a system of equations has solutions or not. Here is one way that is most ideal for most, if not, all equations: using graphs.
- If the graphs of the set of equations do NOT intersect, then there are no solutions (because no x or y value will ever make both equations true)
- If the graphs of the set of equations DO intersect at one point, then ONLY that one point will make both equations true. (One solution)
- If the graphs of the set of equations are identical on the graph, then there are infinite solutions that make both equations true.
Answer:
x = 11
Step-by-step explanation:
ΔLKM is an equilateral because a triangle with all 3 sides that are congruent is an equilateral triangle.
Angles in an equilateral triangle are all 60°.
Thus, ∠L = 60°.
=> 3x + 27 = 60
=> 3x = 33
=> x = 11
The cost of the quesadilla would be $4.75 because $36.35 minute $31.60 equals $4.75.
