Answer:
In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus three over root seven
Step-by-step explanation:
Given that sin ∅ =3/4 It means the ratio of the opposite side to the hypotenuse side is 3:4.
Using the Pythagoras theorem we can calculate the hypotenuse adjacent as follows.
a²+b²=c²
a²=c²-b²
a²=4²-3²
a²=16-9
a²=7
a=√7
Then Cos ∅= opposite/ adjacent
=√7/4
Then Tan ∅ = opposite/adjacent
=3/√7
In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus three over root seven.

Are you trying to figure out what X is? One of the equations equal to 4, and the rest equal to 24.
Answer:
A
Step-by-step explanation:
I agree with you, and since you got the right answer, you would know why.
1700/2890 ≈ 0.5882 = 58.82%
However, usually, you should write about 58.82% as it isn't exactly 58.82
