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}}

Which of the following is a like radical to 3 sqrt 7x?
san4es73 [151]

Answer:

Options A and B

i.e., A. 4(3\sqrt{7x}) and B. \sqrt{7x}

Step-by-step explanation:

Like radicals are similar to like terms.

For example,

x, 2x, -10x, \frac{1}{2} x, 7.3x are like terms.

xy^{2} , -9xy^{2} , 13y^{2} x are some more examples of like terms.

Similarly, like radicals are:

\sqrt{2} , -5\sqrt{2} , 1.1\sqrt{2} etc.

Hence, from the given options, like radicals to 3\sqrt{7x} are:

A. 4(3\sqrt{7x} ) and B. \sqrt{7x}
