the diagram shows a regular dodecagon is the size of one interior angle
The answer is ASA.
Given that ∠A = ∠O, ∠W = ∠N, SW = TN, this shows that the two angles (∠A and ∠W) and the included side SW of the first triangle are equal to the two angles (∠O and ∠N) and the included side TN of the second triangle. This means that third angles ∠S and ∠T are also equal. Therefore, the two triangles ΔWAS and ΔNOT are congruent based from the ASA Postulate.
Answer:
22
Step-by-step explanation:
substitute:
5(7) - 3(8) + 11=0
35 - 24 + 11 = 0
=22
Think of it as a subtraction problem.
-3x -4y = -1
3x - y = -4
_________
0x -5y = -5
y = -5/-5 = 1
Plug 1 in for y in either of the equations
3x -1 = -4
3x = -3
x = -1
Answer: (-1, 1)
