Answer:
The answer is C. AAA is not a congruency postulate because the side lengths may be different sizes although the angles are the same.
0.2 (y+2) = 0.2y + 0.2(2)
= 0.2y + 0.4
Answer: x = -5 1/7
Step-by-step explanation:
-22 - x = 5 + 6x + 9
First, combine the like terms 5 and 9
5 + 9 = 14
-22 - x = 14 + 6x
Add x to each side
-22 = 14 + 7x
Subtract 14 from each side
-36 = 7x
Divide each side by 7
x = -5 1/7 (Yes, a fraction.)
La of sine:
sinC/c = sinB/b==> sin 37°/8 = sin B/12 ==> sin B = 0.903
arcsinB or sin⁻¹ B = 64.5°, & sin (B°) = sin (180° - B°), then
sin(64.5) = sin(180°-64.5°) ==> B = 64.5° or 115.5°
