The central angle measure of the sector is 4.19 rad.
<h3>Area of a Sector</h3>
You need apply the formula: for finding the area of the sector, in radians. In this formula, the variables are:
r= radius
= central angle
The question gives:
A=54 cm²
r= radius= 9cm
Thus, the central angle will be:
For =3.14159..., you have :

Answer:
x = 47
Step-by-step explanation:
86° and 2x° are supplementary angles, which means that added together they should equal 180° (which is a line). Aka
86 + 2x = 180 (Let's solve for x) (subtract both sides by 86 to get x on one side)
2x = 94 (divide both sides by 2 to get x by itself)
x = 47
