Answer:
B
Step-by-step explanation:
Given that r is inversely proportional to s then the equation relating them is
r = 
← k is the constant of proportion
To find k use the condition r = 16 when s = 3
k = rs = 16 × 3 = 48
r = 
← equation of variation → B
Answer:
x = 110°
Step-by-step explanation:
Given that AB = AD then Δ ABD is isosceles and the base angles are congruent, that is
∠ ABD = ∠ ADB = 35°
The sum of the 3 angles in the triangle = 180°, that is
x + 35° + 35° = 180°
x + 70° = 180° ( subtract 70° from both sides )
x = 110°
