Answer:
x = 5.85641
Step-by-step explanation:
Step 1: Find missing leg of left triangle
sin30° = x/16
16sin30° = x
x = 8
Step 2: Find missing leg of right triangle
8² + b² = 16²
b² = 192
b = 8√3
Step 3: Find <em>x</em> by taking the difference
8√3 - 8 = 5.85641
Ratio of Anne : Mark : Ben = 20 : 35 : 25
= 4 : 7 : 5 ( total 16 parts )
Anne = 4/16 x £80 = £20
Mark = 7/16 x £80 = £35
Ben = 5/16 x £80 = £25
