Answer:
2
Step-by-step explanation:
3x+15=21 (the opposite side of parallelogram is equal)
3x=21-15
3x=6
x=6/3
so x=2
AD=2
Answer:
y=3
Step-by-step explanation:
Answer:
x=pi*n/2+1/2arctan(7/5)
Step-by-step explanation:
5sin(2x)=7cos(2x)
5tan(2x)=7/5
2x=pi*n+arctan(7/5)
x=pi*n/2+1/2arctan(7/5) for n e Z
The first one. 1 machine= x 5 mach.=5x. Total time is thus 5x+2/3=1 3/4h. Simply find x by doing 105min-40min/5 and that is 13.
