Two RIGHT angles total 180°.
Acute angles are always under 90°
The measure of the central angle is 4 radians
<h3><u>
Solution:</u></h3>
Given that central angle of a circle intercepts an arc of length 28 centimeters
The radius of the circle is 7 centimeters
<em><u>To find: measure of the central angle in radians</u></em>
The arc length of circle when 
is measured in radians is given as:
Where "s" is the arc length
"r" is the radius of circle
is the central angle in radians
Substituting the values in formula,
Thus the measure of the central angle is 4 radians

Answer:
The final answers are x = 10.385 OR x = -0.385
Step-by-step explanation:
Given the equation is x^2 -4 = 10x
Rewriting it in quadratic form as:- x^2 -10x -4 = 0.
a = 1, b = -10, c = -4.
Using Quadratic formula as follows:- x = ( -b ± √(b² -4ac) ) / (2a)
x = ( 10 ± √(100 -4*1*-4) ) / (2*1)
x = ( 10 ± √(100 +16) ) / (2)
x = ( 10 ± √(116) ) / (2)
x = ( 10 ± 10.77 ) / (2)
x = ( 10 + 10.77 ) / (2) OR x = ( 10 - 10.77 ) / (2)
x = 20.77/2 OR x = -0.77/2
x = 10.385 OR x = -0.385
Hence, final answers are x = 10.385 OR x = -0.385
A = (1/2)*b*h
Base is the vertical length from y1 to y2 = 6
Perpendicular height is the length from x3 to the base = 7
A = (1/2)*6*7
A= 21 units^2
