Answer:
Step-by-step explanation:
sin(7y)=cos(5y+14)=sin(90-(5y+14))=sin(76-5y)
7y=76-5y
12y=76
y=76/12=19/3
or
sin(7y)=cos (5y+14)=sin (90+(5y+14))=sin (5y+104)
7y=5y+104
2y=104
y=52
(0.84, 0.88)
if you round 0.875 you get 0.88
Perimeter = 42 cm
A square has all equal sides so you would just add 10.5 + 10.5 + 10.5 + 10.5 to get 42 cm.
You would write it like -
y = 7 + 4x
or y = 4x + 7
6,000
7 = 7 * 10 = 70
