For a convex polygon with n sides, the sum of interior angles is (n-2)·180°. Thus, the sum of interior angles of a pentagon is (5-2)·180° = 540°.
... x° + 131° + 108° + 107° + 110° = 540°
... x° = 84° . . . . . . subtract 456° from both sides.
The value of x is 84.
The value
which is (c) cannot be the value of sin(∅)
<h3>What is trigonometry?</h3>
Trigonometry is a branch of geometry that relates the sides of a triangle with its angles.
Trigonometric functions are use to establish these relationships and they are: sine, cosine, tangent etc.
Analysis:
All other values are fractions which are less than 0ne when converted to decimal except
which is greater than 1. since the square root of 34 is 5.8 and 5.8/5 is approximately 1.16 and the sine of angles ranges from -1 to 1. so
cannot be a value for sine.
In conclusion, so
cannot be a value for sine.

#SPJ1
Take a look at <span>y = mx^2 – 5x – 2. This is a quadratic equation with a=m, b= -5 and c= -2. What is the discriminant, b^2 - 4ac? (-5)^2 - 4(m)(-2).
There will be 2 complex roots if this discrim. is < 0. Thus, solve
25 + 8m < 0:
Subtr. 25 from both sides: 8m < -25
Div. both sides by 8: m < -25/8
Conclusion: If m is less than -25/8, there will be no real roots (and thus, no x-intercepts). </span>
