Answer:
-35+7u
Step-by-step explanation:
X² - 6x +9 =25
x² -6x -16 = 0
(x+2)(x-8) = 0
x+2 = 0 or x-8 = 0
the answer will be:
x = -2 or x = 8

Answer:
2√2
Step-by-step explanation:
< C = 180-15-45 = 120°
AC/sin 45° = AB/sin 120°
AC = 2√3 × sin 45° / sin 120°
= 2√3 × ½√2 / ½√3
= 2√2
We need to use Law of sine.
sin A/a = sin C/c
sin A/|CB| = sin C/|AB|
sin A/14 = sin(118⁰)/ 20
sin A = (14*sin(118⁰))/ 20
A=arcsin((14*sin(118⁰))/ 20) ≈ 38⁰
