X+1=

To get rid of the square root, put it in the power of 2.
(x+1)^2=3x+7--factor (x+1)^2
x^2+2x+1=3x+7---> solve
<span>Simplifying
6(x + 1) + 5 = 13 + -2 + 6x
Reorder the terms:
6(1 + x) + 5 = 13 + -2 + 6x
(1 * 6 + x * 6) + 5 = 13 + -2 + 6x
(6 + 6x) + 5 = 13 + -2 + 6x
Reorder the terms:
6 + 5 + 6x = 13 + -2 + 6x
Combine like terms: 6 + 5 = 11
11 + 6x = 13 + -2 + 6x
Combine like terms: 13 + -2 = 11
11 + 6x = 11 + 6x
Add '-11' to each side of the equation.
11 + -11 + 6x = 11 + -11 + 6x
Combine like terms: 11 + -11 = 0
0 + 6x = 11 + -11 + 6x
6x = 11 + -11 + 6x
Combine like terms: 11 + -11 = 0
6x = 0 + 6x
6x = 6x
Add '-6x' to each side of the equation.
6x + -6x = 6x + -6x
Combine like terms: 6x + -6x = 0
0 = 6x + -6x
Combine like terms: 6x + -6x = 0
0 = 0
Solving
0 = 0

Answer:
Part I : 100°
Part II : a = 29.2
Part III : b = 20.95
Step-by-step explanation:
See the attached diagram of the triangle.
Part I: ∠ A = 180° - ∠ B - ∠ C = 180° - 45° - 35° = 100°
Part II: Now, applying the law of sines, we have
⇒
⇒
⇒ a = 29.2 (Answer)
Part III: Now, applying law of cosine, we have
b = a cos 35° + c cos 100° = 29.2 cos 35° + 17 cos 100° = 20.95 (Answer)
