First we need to know how much the discount was so 5% is actually 0.05 then we need to multiply it by 53.75 which would equal 2.6875 then subtract it by 53.75 which would equal -51.0625.
B) .95(53.75)
This is a trick question because D) could also be correct if they said you could subtract it but it's not saying use the distributive property.
We are given with three sides with measurements such as below: a = 3.5 cm b = 5.5 cm c = 6 cm We are asked to solve for m∠C. To solve this we need to apply Law of Cosines such as below: cos C = a²+b² - c² /2ab cos C = 3.5² + 5.5² -6² / (2*3.5*5.5) cos C = 0.16883 C = 80.28°
