Answer:
12.9
Step-by-step explanation:
sin 59 = opposite/hypotenuse
opposite is x, the dimension facing the angle 59
hypotenuse is the longest side = 15
sin 59 = x/15
x = 15sin59 = 15 x 0.8572 =12.858 = 12.9 in the nearest tenth
Answer: 30%
percentage = (discount/total amount)
* 100= (8.40/28)*100=30%
x=5, y=3
r= 6p + 20
given:
r= 3n + 20
also given that n = 2p
substituting n=2p into the above equation
r= 3(2p) + 20
