Answer:
50
Step-by-step explanation:
x = √30² - 18² = √576 = 24
tan A = 18/24 = 3/4
∠A = ∠B
tan B = tan A = 24 / y = 3 / 4
y = (24 x 4) / 3 = 32
Z = y + 18 = 32 + 18 = 50
Answer:
See below
Step-by-step explanation:
We shall prove that for all . This tells us that 3 divides 4^n+5 with a remainder of zero.
If we let , then we have
, and evidently,
.
Assume that is divisible by
for
. Then, by this assumption,
.
Now, let . Then:
Since , we may conclude, by the axiom of induction, that the property holds for all
.
