The answer is 6 with 4 remainder
Answer:
sin75º=sin(30)º+45º)
=sin 30 cos 45+cos 30 sin 45
=1/2*√2/2+√3/2*√2/2
=√2/4+√6/4
=(√2+√6)/4
Check with calculator:
sin 75º≈0.9659
exact value=(√2+√6)/4≈0.9659
A. Not a proper counterexample as 3 and 5 aren't the same number. We can rule out choice A.
B. We can rule out choice B since we're not multiplying here
C. We are multiplying the same value with itself but the result is even. We can rule this out.
D. This is a proper counter example. We have the same number (5) multiplied by itself leading to a result that is not even. It contradicts the initial claim.
Answer: Choice D
to make it easier, convert 5 feet to x inches:
5*12=60
60+6=66
So, 66 inches.
Multiply 2.4 by 66:
2.4*66=158.4
So in inches, the answer is 158.4
In feet and inches, 13 feet and 2.4 inches.
