Answer:
sin(theta) + cos(theta) = 0
sin(theta) = -cos(theta)
sin(theta)/cos(theta) = -1
tan(theta) = -1
theta = - 45° ± k·180°
Answer:
if -11i^3 =-11^3 and -11i^3=11i then -11^3=11i
if I'm wrong pls correct me but I'm pretty sure this is
Answer:
I’m sorry what grade is this ?
Step-by-step explanation:
Answer: length = 30, breadth = 15
length = l
breadth = b
l = 2b
2b + b + 2b + b = 90
6b = 90
b = 15
l = 2b
l = 2(15)
length = 30
b = 15
breadth = 15
