JA / JC = AB / BC because, as we can see in the picture above, it's the same proportion. So the answer is the fourth one - BC.
I hope that's what you meant and if so that it will help you :)
Answer:
d = 9/10
Step-by-step explanation:
Hi,
d divided by 5/6 = 3/4
You can't divide fractions, instead, you flip the fraction and multiply. So, in this case, you would flip 5/6 to get 6/5 and multiply it by 3/4 to get d.
d ÷ 5/6 = 3/4
Multiply both sides by 6/5 (remember to flip)
d = 3/4 x 6/5
(when multiplying fractions, you can multiply straight across)
d = 18/20
(simplify - both numbers can be divided by 2)
d = 9/10
Hope this helps :)
The answer is D. Think of the Pythagorean Theorem which states that a^2 + b^2 = c^2. The Pythagorean Identities used in trigonometry are the angle version which can be used to simplify expressions.
Answer:
I don't get it but in my opinion I would say it's 4
