Answer:
C. Yes, we can prove the triangles congruent by SAS.
Step-by-step explanation:
In ∆ABC and ∆DEF,
BC = EF = 6 cm
angle A = angle D = 22°
AC = DF = 14 cm
Hence, the triangles are congruent.
( by SAS congruency criterion )
Answer:
A. A bar magnet’s magnetic field is larger than Earth’s.
Step-by-step explanation:
The average magnetic field strength in the Earth's outer core was measured to be 25 Gauss, 50 times stronger than the magnetic field at the surface.
It is a quadratic
where x-8 is the squared term
do
x-8=u
u^2-13u+30=0
solve
u=

u=

u=

u=

u=

u=

or u=

u=10 or 3
10=x-8 or 3=x-8
18=x or 11=x
x=11 and/or 18
Because there is an "if" this would make it a hypothesis.
