Answer:
question 4
using sine rule:
question 5
using cosine rule:
= 3 5/9
Step-by-step explanation:
2 2/3 × 1 5/7
= 8/3 × 12/7
= (8×12) / (3×7)
= 96/27
= 3 15/27
2 2/3 × 1 5/7 = 3 5/9
548
First, the sides:
7 × 12 = 84
84 × 2 = 168
7 × 10 = 70
70 × 2 = 140
10 × 12 = 120
120 × 2 = 240
Add:
168 + 140 + 240
^ ^
308 + 240
Hope this helped.
C) x also increases 5 times its original value
35/5=7
70/10=7
