Answer:
leg 1 is on 6 see look at the dot thats on x and leg 1 on y is 1 so 6/1 then for number 2 9/5
Answer:
x = 34
Step-by-step explanation:
ΔABD and ΔBCD are both isosceles triangles
In ΔABD
AB =AD, hence ∠ABD = ∠ADB ( base angles are equal )
∠ABD = 
= 
= 68°
∠DBC = 180° - 68° = 112° ( straight angle )
∠BCD = x = 
= 
= 34
