sin 52 cos 13-cos 52 sin 13=sin (52-13)=sin 39
Answer: 31 and 1/9
Step-by-step explanation:
d =29, for g=16,h=9
replace values of each number in equati/on:
d+g/h=29+19/9=(9*29+19)/9=( 261+19)/9=280/9= 31 and 1/9
I can't help u with this but I can give the formula tn=t1+(n-1)+d
Answer:
x=o and y= -6
Step-by-step explanation:
12-2x = - 2(y-x)
or,12-2x = -2y + 2x
or, 12 = - 2y + 4x
or, 12/2= 2x - y
or, 2x - y = 6
• 2x -6= y.....eqn_1
-2x=-2y+2x -12
or,4x +2y= -12
or,4x + 2(2x-6)= -12
or, 4x+4x-12=-12
or, 8x= 0
• x= o
putting the value of x in eqn...3
o=(y-0)+6
or, o= y + 6
•y = -6
