$\bold{\huge{\green{\underline{ Solution}}}}$

$\bold{\underline{ Given :- }}$

<u>We </u><u>have </u><u>given </u><u>a</u><u> </u><u>right</u><u> </u><u>angled </u><u>triangle </u><u>whose </u><u>values </u><u>are </u><u>m</u><u>, </u><u> </u><u>n </u><u>and </u><u>2</u><u> </u>

$\bold{\underline{ To \: Find :- }}$

<u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>value </u><u>of </u><u>m </u><u>and </u><u>n</u>

$\bold{\underline{ Let's \: Begin :- }}$

<u>In </u><u>the </u><u>given </u><u>right </u><u>angled </u><u>triangle</u><u>, </u><u>we </u><u>have </u>

Perpendicular height = n units
Base = 2 units
Hypotenuse = m units

<u>Now</u><u>, </u><u> </u><u>By </u><u>using </u><u>trigonometric </u><u>ratios </u>

$\bold{\pink{ Sin Φ = }}{\bold{\pink{\frac{Perpendicular }{Hypotenuse}}}}$

$\bold{\red{ Cos Φ = }}{\bold{\red{\frac{Base}{Hypotenuse }}}}$

$\bold{\blue { tan Φ = }}{\bold{\blue{\frac{Perpendicular }{Base }}}}$

<u>According </u><u>to </u><u>the </u><u>question </u><u>:</u><u>-</u>

$\bold{ Cos \: 45° = }{\bold{\frac{2}{m}}}$

$\bold{ 1/√2= }{\bold{\frac{2}{m}}}$

$\bold{\red{ m = 2√2 \: units }}$

<u>We </u><u>know </u><u>that </u><u>,</u><u> </u><u>Sum </u><u>of </u><u>Angles</u><u> </u><u>of </u><u>triangle </u><u>is </u><u>1</u><u>8</u><u>0</u><u>°</u><u> </u><u>.</u>

<u>Therefore</u><u>, </u>

Let the unknown angle be x

$\sf{ 45° + x + 90° = 180° }$

$\sf{ x = 180° - 135 ° }$

$\sf{ x = 45° }$

<u>Now</u><u>, </u>

$\bold{ Cos \: x° = }{\bold{\frac{n}{2√2}}}$

$\bold{ Cos \: 45° = }{\bold{\frac{n}{2√2}}}$

$\bold{ 1/√2= }{\bold{\frac{n}{2√2}}}$

$\bold { n = 2√2/√2 }$

$\bold{\red{ n = 2\: units }}$

Thus, The value of m = 2√2 and n = 2

$\sf{\blue{ Hence, \: option \: D \: is \: Correct }}$

What are the coordinates of the point is 1/4 of the way from A (-6, -3) to B (6, 1)?

Amiraneli [1.4K]

Answer:

$(-3, -2)$

Step-by-step explanation:

To find the coordinates of the point is 1/4 of the way from A (-6, -3) to B (6, 1), we are going to be using the midpoint formula, which states that:

The midpoint is at $(\frac{x_{1} +x_{2} }{2}, \frac{y_{1} +y_{2} }{2})$ . Where:

$(x_{1}, x_{2}) = (-6, 6)$

$(y_{1}, y_{2}) = (-3, 1)$

Then, the midpoint is at:

$(\frac{-6 +6 }{2}, \frac{-3+1}{2})$ = $(0, -1)$

Now, to find the coordinates of the point that is 1/4 of the way, we are going to calculate the midpoint between the point 'A' and the midpoint previously caculated, as follows:

$(x_{1}, x_{2}) = (-6, 0)$

$(y_{1}, y_{2}) = (-3, -1)$

⇒ $(\frac{-6 +0}{2}, \frac{-3-1}{2})$ = $(-3, -2)$

Therefore, the point is 1/4 of the way from A to B is: $(-3, -2)$

Natalie Albert deposited checks totaling $1,735,97 into her savings account. She withdrew $100.00 while

givi [52]

Anything withdrawn you subtract. Then, you know the total and you know what you had. Subtract total from what you had and you will see the change.

1735.97-100=1635.97

1668.71-1635.97=32.74
