 Hi, and welcome to the session. I am Deepika here. Let's discuss the question. State whether the following are true or false. Justify your answer. Part 1, the value of 10a is always less than 1. Part 2, secant a is equal to 12 over 5 for some value of angle a. Part 3, cos a is the abbreviation used for the cosecant of angle a. Part 4, cot a is the product of cot and a. 5, sin theta is equal to 4 over 3 for some angle theta. So, let's start the solution. Part 1 is equal to opposite to angle, the value of 10 at this angle. Hypotenuse is the longest side, given secant a is equal to 12 over 5. It is greater than 5. Therefore, the given statement is true, hence the answer for the above part is true. Let's move to the part 3, the abbreviation for sin of angle a. But in the question it is given, cos a is the abbreviation used for the cosecant of angle a. Hence, the given statement is incorrect and the answer for the above part is false. Go to the part 4, the abbreviation used for cot tangent of angle a. It is not the product of cot and a, because cot separated from a has no meaning. Hence, the answer for the above part is false. 5, now sin theta is equal to side opposite to angle theta. We know that hypotenuse is the longest side in a right angle triangle. But we are given sin theta equal to 4 over 3. This implies opposite to angle theta is greater than hypotenuse, which is incorrect, hence the answer for the above part is false. I hope the question is clear to you, bye, take care.
