Question

Thrice of T is decreased by 4

Answer 1

Answer:

Three times a number is represented by 3n . Plus 8 is obvious. "Is" is equivalent to writing "equals".

Answer 2

Step-by-step explanation:

Thrice of T = 3 T

Decreased by 4 . So 3 T - 4

Now, 3 T - 4 = 0

3 T = 4

T = 4 / 3

Trigonometrical way :-

T = 4/3

√T = √4/3

√T = 2/√3

cosec √T = cosec 2/√3

√T = cosec 60°

T = √cosec 60°
