Answer: −a5lx+2a3lx+48 (assuming that the a and the la are variables)
Step-by-step explanation:
48+2xala2−xala4
=48+2a3lx+−a5lx
=−a5lx+2a3lx+48
Each tricycle has 3 wheels and one seat, so the ratio of seats to wheels is 1:3
The answer should be -116
<u>Using Cosine Rule:</u>
5² = 7² + 6² - 2(7)(6) cos(F)
25 = 85 - 84cos(F)
84 cos(F) = 60
cos(F) = 5/7
F = cos⁻¹(5/7)
F = 44°
Answer: 44°
