In ⊙O, ST and VT are tangents. m∠STV = 22°. Find the value of a, b, and m∠SOV.
Rasek [7]

Answer:

\huge \orange {\boxed {a =202\degree}}

\huge \purple {\boxed { b = 158\degree}}

\huge \red {\boxed {m\angle SOV = 158\degree}}

Step-by-step explanation:

In \odot O, ST and VT are tangents at points S and V respectively.

\therefore OS\perp ST, \:and\: OV\perp VT

\therefore m\angle OST=m\angle OVT = 90\degree

In quadrilateral OSTV,

m\angle SOV +m\angle OST+m\angle OVT+m\angle STV = 360\degree

(By interior angle sum postulate of a quadrilateral)

m\angle SOV +90\degree +90\degree +22\degree  = 360\degree

m\angle SOV +202\degree  = 360\degree

m\angle SOV = 360\degree-202\degree

\huge \red {\boxed {m\angle SOV = 158\degree}}

\because b = m\angle SOV

(Measure of minor arc is equal to measure of its corresponding central angle)

\huge \purple {\boxed {\therefore b = 158\degree}}

\because a + b= 360\degree

(By arc sum property of a circle)

\therefore a = 360\degree - b

\therefore a = 360\degree -158\degree

\huge \orange {\boxed {\therefore a =202\degree}}

Illusion [34]

Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−9b2−18b=0

Step 2: Factor left side of equation.

(−9b)(b+2)=0

Step 3: Set factors equal to 0.

−9b=0 or b+2=0

b=0 or b=−2

What is the slope of the line whose equation is 2x-6y=0?
Lina20 [59]
Equation of a line is:

y=mx+C

------------------------

We're looking for m as m stands for gradient.

2x-6y=0 (Divide all terms by 2)

x-3y=0

3y=x

y=1/3x

y=1/3x+0

Therefore m=1/3, C=0.
