Answer:
The answer to your question is -5k⁶
Step-by-step explanation:
Polynomial
- z³ + 5k⁶ - (-z³ + 10k⁶)
Use law of signs for the parenthesis
- z³ + 5k⁶ + z³ - 10k⁶
Use associative property for like terms
(-z³ + z³) + (5k⁶ - 10k⁶)
Simplify like terms
(0) + (-5k⁶)
Result
-5k⁶
Answer:
The height of the building is approximately <u>73 m</u>.
Step-by-step explanation:
The triangle EFG is shown below.
Given:
Length of shadow of building is, 
Angle of inclination of Sun with the vertical is 25°.
Therefore, the angle of inclination of Sun with the horizontal is given as:

Now, in triangle EFG as shown below, we use the tangent ratio to determine the height of building EF. Therefore,

Therefore, the height of the building is approximately 73 m.
Triangles are 180 degrees total so 80+40=120, subtract that from 180 and you’ll get B=60
