Answer:
Either of ...
- (x, y) ⇒ (-x, -y)
- Rotation 180° about the origin
Step-by-step explanation:
There are at least two ways to express the transformation that maps each coordinate to its opposite.
1. reflection across the origin: (x, y) ⇒ (-x,-y)
2. rotation 180° (either direction) about the origin.
Take your pick.
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:
25.59
Step-by-step explanation:
The first thing that you will do is solve parenthesis (remember PEMDAS).
(32.45-4.8) - 2.06
(27.65) - 2.06
Then do the subtraction.
(27.65) - 2.06=
25.59
Hope this helps!
