Hello I am once again asking for help ASAP

Mathematics
1 answer:
nadezda [96]3 years ago

Answer:

23.7°

Step-by-step explanation:

To obtain the value of AB ; Use the cosine rule ;

Recall:

c² = a² + b² - 2ab Cos C

c² = 24² + 11² - 2*24*11 Cos75

c² = 576 + 121 - 528 * 0.2588190

c² = 697 - 136.656432

c² = 560.343568

c = sqrt(560.343568)

c = 23.6715

Hence, c = AB = 23.7°

30/40 say no, so x/1000 would say no. 1000/40=25, 25*30=750. So, about 750 would dislike it.

PLEASE HELP ASAP WILL MARK BRAINLIEST<br><br> Solve the quadratic equation <br> 18x^2 -153x -172 =0
Vika [28.1K]

Answer:

The answer is : x = 9.505 and x = -1.005

Step-by-step explanation:

To solve the quadratic equation use the formula :

x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}

Where a is the coefficient of x² , b is the coefficient of x and c is the numerical term

∵ a = 18 , b = -153 and c = -172

∴ x=\frac{-(-153)+\sqrt{(-153)^{2}-4(18)(-172) } }{2(18)}

x = \frac{18+\sqrt{35793} }{36} &x=\frac{18-\sqrt{35793} }{36}

∴ x = 9.505 and x = -1.005
