Ulipoingiza neno LBDA.. ndo ulipomuondoa huyo form one....
Ulipoingiza neno LBDA.. ndo ulipomuondoa huyo form one....Kwa nini da (Engeneer) mbona hata form one anaweza? Akijua simultaneous equation mambo yote. Labda logic ya kupanga hizo equation

ngoja nikacheck kwenye Kalikuleta ya simu yangu kama nitaweza pata jibu.
x=31, y=3.92SOLUTION
Since angle BCD=124°
angle<ACB = 180-124=56°
angle <ACB=56°
Since line AC= line BC
Then <CAB= <ABC
Recall angle ACB = angle ABC=124°
Then angle CAB =62°
angle ABC =62°
from angle CAB=2X°
2X°=62°
X=31
From angle ABC=(14Y+6)°
( 14Y+6)°=62°
14Y=62-6
14Y=56
Y=4
ANSWERS X=31 ,Y=4

Awali ya yote pembetatu ABC ni pacha

Yeah,Equilateral Triangle!Sure x=31 na y=4
Mkuu hapa jibu ni D
Solution.
Kwa simultaneous equation
Siyo kwelii mkuuSolution.
From general equation,
3X-Y=12
let y be 0
Then 3X=12
X=4
Let x be 0
Y=12
Then from the required equation
x
8
_________
y
2
Since X = 4 ,Y =12
8⁴
_______
2¹²
Then
( (2)³)⁴)
___________
(2)¹²
(2)¹²
__________
(2)¹²
=1
So the correct answer is D.
*kaka jambazi* njoo uni correct if am wrong. Dah hizi hesabu nakumbuka nilipokuwa form one nilizipiga sana yaani.
