The value of the expression sec (-π) is equal to -1 if the given expression is undefined.
As given in the question,
Given expression: sec (-π)
Standard position of unit circle: -π is representing semicircle with terminal point on negative x-axis with coordinates (-1, 0)
Hypotenuse = √ (-1)² + 0²
= 1
Value of the expression is given by
sec α = Hypotenuse / Base (x-coordinate)
⇒sec(-π) = 1 / -1
⇒sec(-π) = -1
Therefore, the value of the expression sec (-π) is equal to -1.

I'd say that 6300 is greater than 530
i'd also say the 530 is less than 6300
i'd also say 6300 is 11.88679245 . . times greater than 530
and that 530 is 0.0841269841 times as great as 6300
i'd say that 530 has a 3 in it and so does 6300, except that the 3 in 530 is in the tens place, and the 3 in 6300 is in the hundreds place
i'd say . . . . (on and on I could go)

By exterior angle theorem.
90+x=2×58
X=116-90=26.

This is a isosceles triangle. all sides degrees added together (triangle) is equal to 180.
we know one side is 55°, and since its isosceles, it will be congruent on both sides. so there are 2 55°.
since the sum of all angles is 180°, the equation will be 55°+55°+x=180
combine like terms (55+55), which equals to 110.
last, 180-110 = 70
so the answer will be x = 70°
