Answer:
The angle in the upper right quadrilateral corner = 68 degrees because vertical angles are equal.
Angle Y = 68 (opposite quadrilateral angles are equal).
All quadrilateral angles add to 360 so:
68 + 68 + x + z = 360 = 292
angle X + Z = 292
Therefore angle x = angle z = 146
Step-by-step explanation:
angle Z = 68 degree (being alternate angles)
angle X = 68 degree (opposite angle of a parallelogram is equal)
y + z = 180 degree (sum of adjecent angles of a parallelogram is 180 degree)
y + 68 = 180
y = 180 - 68
y = 112 degree
Answer:18/5

one solution
f(x) = 9 * 81^x
When x = -1/2,
f(-1/2) = 9 * 81^(-1/2) = 9 * (1/9) = 1.
