Answer:
3) 5
4) 8.2
5) 6.8
6)FG = 6.4
7) EF = 3.6
8)DF = 4.8
Step-by-step explanation:
From the attached triangle, using trigonometric ratio we can find ∠G as; tan^(-1) (6/8)
Thus, ∠G = 36.87°
Still using trigonometric ratios;
FG/8 = cos 36.87°
FG = 8 cos 36.87°
FG = 6.4
3) EF + FG = EG
Since EG is 10, mean of EF and FG = 10/2 = 5
4) mean of EG and FG = (10 + 6.4)/2 = 8.2
5) EF + FG = EG
Thus; EF = EG - FG
EF = 10 - 6.4
EF = 3.6
Mean of EG and EF = (10 + 3.6)/2 = 6.8
6) FG = 6.4
7) EF = 3.6
8) Using trigonometric ratio;
DF/8 = sin 36.87
DF = 8 × 0.6
DF = 4.8

Answer:
triangles AQB and AVB are congruent.
ΔLKJ ≅ ΔLMJ
Step-by-step explanation:
We have to prove that triangles LKJ and LMJ are congruent so let's
Consider triangles LKJ and LMJ;
∠KLJ=∠MLJ {Given that LJ bisects ∠KLM}
∠KJL=∠MJL {Given that LJ bisects ∠MJK}
LJ=LJ {common side}
So using ASA, triangles AQB and AVB are congruent.
Hence it is proved that
ΔLKJ ≅ ΔLMJ
