1) mesure of an arc= R.Ф, where R is the radius & Ф the angle <span>IN RADIAN
32</span>°===>8π/45 OR 0.5585, So mes of Arc CD = 6x0.5585 = 3.35 cm
2) DAC = 31° & CAD =27° , these 2 angles being adjacent I can write that
Angle(DAC +CAB=DCB) ==>Angle DCB =(31°+27°=58°)
To remember that any vertex of an angle on the circles, its sides intercept an arc which mesure is twice the angle,
Hence since mes Angle DCB=58°, that means the ARC intercepted, namely DB has a length of 2x 58 = 116°
Answer:
6
Step-by-step explanation:
the middle number of the given list
Answer:
(5, - 2)
Step-by-step explanation:
2x+y>3
x-y>1
2x + y > 3 - - - - (1)
x - y > 1 - - - (2)
Using trial and error method :
Using :
(5,-2)
2x + y > 3
2(5) + (-2) > 3
10 - 2 > 3
8 > 3 (true)
x - y > 1
5 - (-2) >1
5 + 2 > 1
7 > 1 (True)
For 0,5
2x + y > 3
2(0) + (5) > 3
0 + 5 > 3
5 > 3 (true)
x - y > 1
0 - (5) >1
-5 > 1
--5 > 1 (false)
Also, all other options do not hold true for bitb inequality statements, hence answer is (5, - 2)
