Answer:
L=62.5 W=12.5
Step-by-step explanation:
L=5W
150=2W+2(5W)
75=W+5W
75=6W
W=12.5
12.5×5=62.5
62.5+62.5+12.5+12.5=150

Answer:
A. 17
Step-by-step explanation:
using the cosine rule (also see attached for reference):
AB² = BC² + AC² - 2·AC·BC cos C
2·AC·BC cos C = BC² + AC² - AB²
Given that AC = 18, AB = 12 and BC = 18, substituting these into the formula
2(18)(28) cos C = 28² + 18² - 12²
1008 cos C = 964
cos C = 964/1008
cos C = 0.9563
C = cos⁻¹ 0.9563
C = 16.99 ( = 17° rounded to nearest degree)
