Answer:
see explanation
Step-by-step explanation:
since the triangles are congruent, then corresponding angles are congruent.
∠ B = ∠ F
∠ FCE ≅ ∠ BDA
∠ EFC ≅ ∠ ABD
∠ FEC ≅ ∠ BAD
note that the order of letters in Δ ABD follows the same order as those in Δ BDA
Answer:
20 points
Step-by-step explanation:
Points:
- 21, 13, 14 and x for the last game
Average:
- (21+13+14+x) / 4 = 17
- 48 + x = 4*17
- 48 + x = 68
- x = 68 - 48
- x = 20
They must score 20 points
Answer:
-1+√6
-1-√6
Step-by-step explanation:
x²+2x-5=0
x=(-2±√(2²-4(-5)))/2=(-2±√(4+20))/2=(-2±√24)/2
x₁=(-2+√24)/2 or x₂=(-2-√24)/2
x₁=(-2+2√6)/2 or (-2-2√6)/2
x₁=-1+√6 or x₂=-1-√6
