Answer:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = ( multiply both sides by 8 )
56 = k
P = ← equation of variation
When x = 7 , then
P = = 8

Step-by-step explanation:
In a rectangle
• All angles are right angles
• the diagonals are congruent
In Δ WXV the sum of the 3 angles = 180°
∠ WXZ = ∠ XWY = =
= 58°
∠ YXZ = 90° - 58° = 32°
∠ WVZ = 180° - 64° = 116° ( adjacent angles are supplementary )
∠ XWZ = 90° ( by definition of rectangle )
∠ XZY = ∠ WXZ = 58° ( corresponding angles )
