Answer:
x=0.4, x=-1.2
Step-by-step explanation:
Increased by 25% OR 1/4
50 times 1/4=50/4=12.5 increase
50+12.5=62.5 per month
money per month times number of months=money
62.5 times ?=375
divide both sides by 62.5
?=6
6 months
Answer:
45.6° (1 d.p)
Step-by-step explanation:
Using the cosine rule;
c = √( a² + b² - 2ab Cosx)
11 =√(8² + 15² - 2 (8) (15) Cosx)
11² = 8² + 15² - 240 Cosx
11² - 8² - 15² = - 240 Cosx
-168 = -240 cosx
cosx = 0.7
x = cos⁻¹ (0.7) = 45.57 ≈ 45.6°
