Answer:
1. None of the angles
2. Is not
3. Is not
Step-by-step explanation:
We can see if the triangles are congruent by ASA (angle, side, angle)
We find ∠F in DEF by 180-(64+78)=38 and 38 doesn't equal 39 so they are not congruent.
8.9 + 3.4 -1.4x - 6.5x = 12.3 - 7.9x
Answer:
4 units
Step-by-step explanation:
according to question:
perimeter of square = 16 units
4a = 16
where a is the side length
a = 16/4
= 4 units
D = √( (x₂ -x₁)² + (y₂ - y₁)²)
x₁ = 10, y₁ = -9, x₂ = 8, y₂ = 7
d = √( (x₂ -x₁)² + (y₂ - y₁)²)
d = √( (8 - 10)² + (7 - -9)²)
d = √( (-2)² + (7+9)²)
d = √( (-2)² + (16)²)
d = √(4 + 256)
d = √260 Use a calculator
d ≈ 16.1245
d ≈ 16.12 units to the nearest hundredth.
Option D.
Answer:
y==$281+$166=$447
in 11 weeks she pay $ 447
in 1 weeks she pay $447/11=40.6$
she paid off in 3+8=11 weeks
