Answer:x=-5.5
Step-by-step explanation:
The answer
<span>a rational number that is between 5.2 and 5.5
first, </span><span>a rational number is a decimal number that the number after the dot can be ended. for example
1/2 = 0.5 is rational, 2 is rational because 2 = 2. 0,
so a rational number </span>between 5.2 and 5.5 can be 525 /100
because this rational number can be written as 525 /100 = 5.25
and 5.2 less than 5.25 less than 5.5
an irrational number is a decimal number that the number after the dot cannot be ended. for example 1/3 = 0.3333333333......
so so an irrational number between 5.2 and 5.5 can be √30
because √30 can be written as √30 = 5,477225575051661134569........
and 5.2 less than 5.47 less than 5.5
Answer:
See explanation
Step-by-step explanation:
The given trigonometric equation is 
.
We take the inverse cosine of both sides to get:
