In triangle WYX , segment YZ is an altitude , an angle bisector or a median?

vazorg [7]

Line segments are bounded by two endpoints

The line segment YZ is a median

<h3>How to determine what segment YZ is?</h3>

From the complete question, the point Z is on line segment WX, where:

Segments WZ and XZ have equal measurements

This means that, segment YZ divides segment WX into equal segments

When a segment is divided into equal segment by a line, then the line is a median

Hence, segment YZ is a median

I need help on this please

Eduardwww [97]

Answer:

a= k=15 c= m=48/7

Step-by-step explanation:

for a.

first, collect like terms. calculate.

2k- 10 = 20

move the constant to the right (10)

2k = 20 + 10

2k = 30

divide both sides.

k= 15.

for c.

first calculate.

12= 3m - 2/3m - 4

multiple both sides.

36= 9m - 2m - 12

collect like terms.

36= 7m - 12

move like terms.

-7m= - 12 - 36

calculate.

-7m= - 48

divide both sides.

m=48/7

Given that tan^2 theta=3/8,what is the value of sec theta?

Alex Ar [27]

Answer:

The value of SecФ is $\pm \sqrt{\frac{11}{8}}$ .

Step-by-step explanation:

Given as for trigonometric function :

tan²Ф = $\frac{3}{8}$

Or, tanФ = $\sqrt{\frac{3}{8} }$

∵ tanФ = $\frac{Perpendicular}{Base}$

So, $\frac{Perpendicular}{Base}$ = $\sqrt{\frac{3}{8} }$

So, Hypotenuse² = perpendicular² + base²

or, Hypotenuse² = ( $\sqrt{3}$ )² + ( $\sqrt{8}$ )²

Or, Hypotenuse² = 3 + 8 = 11

Or, Hypotenuse = ( $\sqrt{11}$ )

Now SecФ = $\frac{Hypotenuse}{Base}$

or, SecФ = $\frac{\sqrt{11}}{\sqrt{8}}$ = $\sqrt{\frac{11}{8} }$

<u>Second Method</u>

Sec²Ф - tan²Ф = 1

Or, Sec²Ф = 1 + tan²Ф

or, Sec²Ф = 1 + $\frac{3}{8}$

Or, Sec²Ф = $\frac{11}{8}$

Or, SecФ = $\pm \sqrt{\frac{11}{8}}$

Hence The value of SecФ is $\pm \sqrt{\frac{11}{8}}$ . Answer

What is the value of the expression, written in standard form?

Studentka2010 [4]

Answer:

The value of the expression = 200

Step-by-step explanation:

The given expression is $\frac{6.6 * 10^{-2}}{3.3*10^{-4}}$

Using the low of exponent $x^{a} /x^{b} = x^{a-b}$

So, the expression =

$\frac{6.6 * 10^{-2}}{3.3*10^{-4}} = \frac{6.6}{3.3} * 10^{-2 -(-4)} = 2 * 10^{2} = 2*100=200$

<u>So, The value of the expression = 200</u>
