Craig has £13.40 he sees this offer in a restaurant : main courses £8.90 each.buy one main course and get the second half price. can he afford to buy two main courses? show your working

Yes

Step-by-step explanation:

Full price for first course:  £8.90

Half price:                           £4.45

One and one half times

 full price is then:             £13.35

Since this is less than Craig's £13.40, he can just barely afford to buy two main courses at these prices.

22.62°

Step-by-step explanation:

Looking at the attached diagram, it is a right angled triangle. If we are to solve for the measure of angle x , we would be using the Trigonometric function of cosine

The formula is given as

cos x = Adjacent/ Hypothenuse

Adjacent = 12

Hypothenuse = 13

Therefore,

cos x° = 12/13

x° = cos -¹ (12/13) or arccos (12/13)

x° = 22.619864948°

Therefore, the measure of x to the nearest hundredth = 22.62°
