The perimeter of a regular pentagon with side length of 1.2 cm is 5(1.2) = 6 cm.
Answer:
take 42 degree as reference angle
using sine rule
sin 42=opposite/hypotenuse
0.66=x/23
23*0.66=x
15.18=x
15.2=x
take x degree as reference angle
using cos rule
cosx=adjacent/hypotenuse
cosx=29/42
cosx=0.69
cos 46 =0.69
therefore x=46 degree
Step-by-step explanation:
It will be irrational. The sum of any irrational and rational number will ALWAYS result in a irrational answer. Khan Academy has a video on this if you want to watch it.
They focus on the use of precisely written legal contacts
