Answer:
7/20 = x/400
Step-by-step explanation:
First of all we have to find the cost of a book then multiply it by 5 :
$ 11.20 ÷ 8 = $ 1.4
$ 1.4 × 5 = $ 7

Answer:
56.96°
Step-by-step explanation:
The set up will give a right angles triangle where;
The height of the sky scraper = hypotenuse side = 396m
The length of the shadow will be the opposite = 332m
According to the SOH trig identity
sin theta = opp/hyp
sin theta = 332/396
sin theta = 0.8383
theta = arcsin 0.8383
theta = 56.96°
Hence the sun is at 56.96° above the horizon
