Answer:
y = 46
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 23 when x = 8 , then
23 = ( multiply both sides by 8 )
184 = k
y = ← equation of variation
When x = 4 , then
y = = 46
Answer:
Its a right angle triangle so trigonometry is used.
