Answer:
=60 the second option.
Step-by-step explanation:
Given the trigonometric ratio, we can find the value of the angle by simply finding the inverse of the given ratio.
If for example Cos ∅= a, then ∅=Cos⁻¹a
If Cos (x)= 0.5, then x= Cos⁻¹ 0.5
Cos⁻1 0.5=60°
The angle whose sine is 0.5 is ∅=60°
Answer:
£210
Step-by-step explanation:
Given that :
Visa cost = £2300
7% charge of visa price = (0.07 * £2300) = £161
Total cost = £(161 + 2300) = £2461
Amount to be saved per month = £2461 / 12 = £205.08333
= £210 (nearest £10)
