Answer:
18.4°
Step-by-step explanation:
Use law of cosine.
a² = b² + c² − 2bc cos A
11² = 20² + 28² − 2(20)(28) cos A
121 = 1184 − 1120 cos A
cos A = 0.949
A = 18.4°
Answer :
Length of rectangle = 14m
Width of rectangle = 12m
Explanation :
p = 2l + 2w = 68
l = w + 2
Substitute:
68 = 2(w + 2) + 2w
68 = 2w + 4 + 2w
4w = 64
w = 16
l = 18
