Answer:
Step-by-step explanation:
1). Geometric mean of a and b =
Therefore, geometric mean of 2 and 50 =
= 10
2). By geometric mean theorem,
e² = 6 × 24
e = √144
e = 12
Similarly,
d² = 6 × 30
d = √180
d = 6√5
And
c² = 30 × 24
c = √720
c = 12√5

we know that
in rectangle ABCD
AB=CD
and
AD=BC
therefore
the triangle ACD and triangle ABC are congruent
so
BD=AC
BD=8 units
the answer part a) is
BD= 8 units
Part b) Find angle CBD
we know that
∠ABD+∠CBD=90°---------> by complementary angles
so
∠CBD=90-∠ABD-----> 90-67----> 23°
∠CBD=23°
the answer Part b) is
∠CBD=23 degrees
