Answer:
x = 12.5
Step-by-step explanation:
The given triangle is a right angle triangle.
We cannot use the Pythagoras theorem as the lengths of all sides are not known. We will use triangular ratios here to solve the given problem.
As it is clear from the diagram that x is the hypotenuse of the triangle and 11 is the length of the base. We will use a ratio in which base and hypotenuse are used.
So,
cos θ= base/hypotenuse
cos 28=11/x
x=11/cos28
x=11/0.8829
x=12.45
Rounding off to nearest 10
x=12.5
Its already in simplest form its already right
The sum of the three interior angles would be 180°
Hope this helped

Step-by-step explanation:
_____
Good evening ,
_______________
I guess The right answers are A and B
Because when we add an rational to an irrational we get an irrational
You should notice that 2π and -√17 are irrationals.
