For this case we must find the value of the following expression:
-3 + 9 * 8÷2 =
According to the PEMDAS algebraic order of operations:
P: Perform any calculation within parentheses
E: Simplify any exponential expressions.
MD: Do all the multiplications and divisions, from left to right, as they appear.
AS: Do all the addition and subtraction, from left to right, as they appear.
So:
49-3 + 9 * 8÷2 =
49-3 + 72÷2 =
49-3 + 36 =
46 + 36 =
82
ANswer:
82

The value of each measure based on the incenter is illustrated below.
<h3>What is incenter?</h3>The incenter of a triangle is the point of intersection of all the three interior angle bisectors of the triangle. This point is equidistant from the sides of a triangle.
Angle ARU = 40 degree
Length of AU = 20
Angle QPA = 35 degree
Since, AR is angle bisector of angle URK.
So, ∠ARU = ∠ARK = 40 degree
Since, incenter point is equidistant from the sides of a triangle.
So, AT = AU = AK = 20
Since, PA is angle bisector of angle QPU.
So, ∠QPA = ∠UPA
3x + 2 = 4x - 9
4x - 3x = 9 + 2
x = 11
Substituting value of x in angle 3x + 2
We get, ∠QPA = 3(11) + 2 = 35°
