puteri [66]

Answer:

Step-by-step explanation:

(1)The units for measuring angles are degrees and radians

A circle is 360° which is equal to 2π radians

1°=π/180

To convert angle measurement from degrees to radians multiply the value of degrees by π/180

(11)

To convert angle measurement from radians to degree multiply the value of radian by 180/π

(111)Yes it matters because you will use different formulas to calculate the length of the arc

For example , when the central angle is in radians, the formula to apply is;

⇒     S=rФ -------------where  r is the radius of circle and Ф is angle in radians and S is the arc length.

⇒   When the central angle value is in degrees , the formula to apply is

Arc length =2πr×(Ф/360) where Ф is in degrees , r is radius of circle

2. sin\frac{17\pi }{6} \\

we know π=180°

hence 17/6 π=?---------------cross multiply

\frac{17\pi }{6} *180\\\\\\=17\pi *30\\\\\\=510\pi

Apply trigonometry

Find sine 510°

Sine (510°-360°)= sine 150°

Sine 150° = sine 30° = 1/2-----------------2nd quadrant

This means sine 510° = 1/2

Find all complex solutions of 5x^2-6x+2=0.
gregori [183]
We use quadratic formula for that one
remember that √-1=i

so

for
ax^2+bx+c=0
x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}
so
given
5x^2-6x+2=0
a=5
b=-6
c=2

x=\frac{-(-6)+/-\sqrt{(-6)^2-4(5)(2)}}{2(5)}
x=\frac{6+/-\sqrt{36-40}}{10}
x=\frac{6+/-\sqrt{-4}}{10}
x=\frac{6+/-2i}{10}

x=\frac{3}{5}+\frac{i}{5}, \frac{3}{5}-\frac{i}{5}
