Define x♣y♣z as follows: x♣y♣z = x + y + z 3 Evaluate: 1000♣-2000♣1000

Step-by-step explanation:

hello :

x♣y♣z = x + y + z 3

Evaluate: 1000♣-2000♣1000

put x = 1000  and y = -2000  and z = 1000

1000♣-2000♣1000 = 1000-2000 +1000^3

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
