Answer 1

Answer:

hope my answer is correct and it will help you

please give me thanks

Answer 2

Explanation:

As given, sin theta = 2/3

Sin theta = Side Opp. / Hypotenuse

= 2/3

We know that the hypotenuse of a right angle triangle is equal to the square roots of the sum of the squares of the remaining two sides. It is also known as the Pythagoras Theorem. It can be denoted as,

Hypotenuse = √Opposite^2 + Adjacent^2

According to the question,

√3^2 - 2^2 = Side adjacent

or, √9 - 4 = √5 = Side adjacent

Cos theta = Side adjacent / Hypotenuse

= √5/3

Answer:

Cos theta = √5/3
