Answer:
x = 11
z = 104
Step-by-step explanation:
opp angles are equal & sum of angles at apoint, will help next time.
D. $8.15=100% what about 120% because percentage increase you add you have increase to 100.
Polar form of a complex number is r( cos(theta) + i sin(theta) )
r is equal to the total distance created by the rectangular coordinates of the complex number
r = Root(4^2 + (-4)^2) = Root(32) = 4 Root(2)
To find theta, if a > 0, use arctan(b/a), where:
a = the first number
b = the second number
arctan (-4/4) = -45 degrees (-0.7854 radians)
Your answer is 4 Root(2) (cos(-45) + i sin(-45))
803.84 is the answer. The formula is 4×3.14×r(sqaured) and I'm assuming by axis you were talking about the diameter so 16÷2=8 so 8 is the radius. 8×8=64. 64×4=256. 256×3.14=803.84
