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.
Answer: x= 3
Step-by-step explanation:
2x + 5 = 11
2x = 6
x = 3
Answer:
54 is anwer.
please mark me brainliest and follow me my friend.
because 54 is correct answer.
6x2 + x - 7
= (6x + 7)(x - 1)
So, the answer is (6x + 7), or C.
