S_A_V [24]

Answer:

Step-by-step explanation:

Using the cosine theorem:

$c^{2} =a^{2} +b^{2} -abcos\beta$

$952^{2} =560^{2} +575^{2} -560*575cos\beta$

$\beta =cos^{-1} (\frac{560^{2}+575^{2}-952^{2} }{2*560*575} )$

The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees

Answer:

see explanation

Step-by-step explanation:

(a)

2x + 10 ← factor out 2 from each term

= 2(x + 5)

(b)

5x - 15 ← factor out 5 from each term

= 5(x - 3)

(c)

8x + 6 ← factor out 2 from each term

= 2(4x + 3)

(d)

12x - 8 ← factor out 4 from each term

= 4(3x - 2)
