8. A number whose fifth part is increased by 5 is equal to its fourth part diminished by 5 . find the number

the number = X

fifth part = X/5

fifth part is increased by 5 = X/5 + 5

fourth part = X/4

fourth part diminished by 5 = X/4 - 5

fifth part is increased by 5 is equal to its fourth part diminished by 5

X/5 + 5 = X/4 - 5

X/5 - X/4 = - 5 - 5

(4X - 5X)/20 = - 10

- X/20 = - 10

X = 200

Check:

X/5 + 5 = X/4 - 5

200/5 + 5 = 200/4 - 5

40 + 5 = 50 - 5

45 = 45

Answer:

Answer:

50.2

Step-by-step explanation:

$ut = \sqrt{ {6}^{2} + {5}^{2} } \\ \sqrt{36 + 25} \\ \sqrt{61 } \\ using \: cosine \: rule \\ cos \: u = \frac{ {5}^{2} + 61 - 36 }{2 \times 5 \times \sqrt{61} } \\ \\ = \frac{25 + 61 - 36}{78} \\ \\ = \frac{50}{78 } \\ \cos \: u = 0.64 \\ m∠U. = 50.2$
