Answer:
y = 4
Step-by-step explanation:
Given that y varies jointly with x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 16 when x = 4 and z =
, that is
16 = k × 4 ×
= 2k ( divide both sides by 2 )
8 = k
y = 8xz ← equation of variation
When x = 2 and z =
, then
y = 8 × 2 ×
= 16 ×
= 4
Knowing that the angles of the triangle has a total of 180 degrees, so we can have the following:
x + y + z = 180
y + z = 180 - x
or
x = 180 - y - z
In this approach, we can't give the actual values since there are no values presented.
