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
Answer:
2187
Step-by-step explanation:
3^3 = 27
3^4 = 81
27 x 81 = 2187
The answer is x= -10. To get this answer you have to simplify both sides of the equation, distribute, and combine the like terms. The second step is to add 15/2x to both sides. Step 3 is to subtract 72 from both sides, then divide both sides by 3
