Answer:
<u>C </u>
Step-by-step explanation:
If the function equation is F(x)=3x. You just plug in the 3 from F(3) in for the x.
F(x)= 3x
↓
F(3)=3(3)
F(3)=9
Answer:
Step-by-step explanation:
Find the volume first.
V= l * w * h
l = 2 cm
w = 3 cm
h = 1 cm
V = 2 * 3 * 1 = 6 cm^3
Density = mass / volume
Density = 420 grams / 6 cm^3
Density = 70 grams / cc^3
Kind of large. Check your givens.
Answer:
∡CFE and ∡BFD, ∡AFB and ∡BFD
Step-by-step explanation:
It is because supplementary angle is straight lines which add ups to 180°
Therefore, ∡CFE and ∡BFD, ∡AFB and ∡BFD are supplementary angles
Answer:
15
Step-by-step explanation:
Opposite angles, angles that are opposite each other when two lines cross, are also known as vertical angles because the two angles share the same corner. Opposite angles are also congruent angles, meaning they are equal or have the same measurement.
Therefore 60 = x + 45 or 60 - 45 = x =15
we know that
<u>Alternate interior angles</u> are two interior angles which lie on different parallel lines and on opposite sides of a transversal. Alternate interior angles are congruent
see the attached figure with letters to better understand the problem
in this problem
the parallel lines are the lines a and b
the transversal line is the line c
so
the alternate interior angles are the Angle
and Angle 
m∠3=m∠6
therefore
<u>the answer is the option</u>
Angle
and Angle
