cos (3</span>π/4) = -√2 / 2
sin ((3π/4) = √2 / 2
cos (3π/4) and sin ((3π/4) = -√2 / 2 * √2 / 2

Answer:
48.69
Step-by-step explanation:
LMO+NMO = LMN,
x+34 + NMO = 6x-28
But, MO bisects LMN, so LMO=NMO
x+34 + x+34 = 6x-28
2x+68 = 6x-28
4x = 96
x = 24
That would makem it
24 + 34 =58 T NMO = 6(24)-28
58 + nmo = 144 - 28 = 119
116- 58 = 58
um what
sory not understand from finland good luck
<span>The identity element when applied does not change the other elements hence in multiplication 1x7=7 and 1x5=5 the elements 5 and 7 do not change for addition its 0 such as 0+10=10.
</span><span>Identity for multiplication is 1, for addition its 0</span>
