Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180
x = 180° - (90 + 35)° = 180° - 125° = 55°
----------------------------------------------------------
Since the triangle is right use the cosine ratio to solve for b
cos35° =
= 
Multiply both sides by 20
20 × cos35° = b, hence
b = 16.38 ( to 2 dec. places )

Answer:
credit gain by retailer is $2257.39
Step-by-step explanation:
Given data:
Retaile price 83 4/3 c or 84.33c
Let Discount rate 6/7
Discount amount = (6/7)% of 84.33 c = 0.7228 C
Net credit received = 84.33c - 0.7228c = 83.607c
Net credit received = 83.607 c
Item required = 2700
Total discount = 2700 × 83.0607 = 225739.44c
Total discount = $2257.39
credit received by retailer is $2257.39
