\boxed{ \sf{Answer}}

\large{\sf\frac{a + 1}{a - 1}  +  \frac{ {a - 1}^{2} }{a + 1}}

Use the algebraic identities ⟶

  1. {\sf(a - b)(a + b) =  {a}^{2}  - b ^{2}}
  2. {\sf(a + b) {}^{2}  =  {a}^{2}  + 2ab -  {b}^{2}}
  3. {\sf(a - b) {}^{2}  =  {a}^{2}  - 2ab +  {b}^{2}}

Squaring on both the sides

{\sf\frac{(a + 1 {)}^{2}  + ( {a - 1)}^{2} }{(a - 1)(a + 1)}}

=\frac{ {a}^{2} + 2a + 1 +  {a}^{2} - 2a + 1  }{ {a}^{2} - 1 }  \\  =  \frac{ {a}^{2} +\bcancel 2a + 1 +  {a}^{2} - \bcancel2a + 1  }{ {a}^{2} - 1 } \\  =   \frac{ {a}^{2} +  {a}^{2} + 1 + 1  }{ {a}^{2}  - 1}

\large\boxed{\sf{⟹\frac{ {2a}^{2}  + 2}{ {a}^{2} - 1 }}}

Ms. Mwanted to estimate the height of the Republic Plaza building in downtown Denver. She has an app on
Volgvan

Answer:

<em>The height of the bullding is 717 ft</em>

Step-by-step explanation:

<u>Right Triangles</u>

The trigonometric ratios (sine, cosine, tangent, etc.) are defined as relations between the triangle's side lengths.

The tangent ratio for an internal angle A is:

\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}

The image below shows the situation where Ms. M wanted to estimate the height of the Republic Plaza building in downtown Denver.

The angle A is given by his phone's app as A= 82° and the distance from her location and the building is 100 ft. The angle formed by the building and the ground is 90°, thus the tangent ratio must be satisfied. The distance h is the opposite leg to angle A and 100 ft is the adjacent leg, thus:

\displaystyle \tan 82^\circ=\frac{h}{100}

Solving for h:

h = 100\tan 82^\circ

Computing:

h = 711.5 ft

We must add the height of Ms, M's eyes. The height of the building is

711.5 ft + 5 ft = 716.5 ft

The height of the building is 717 ft

How do you write 4/6 as a unit fraction
lawyer [7]

Answer:

1/6

Step-by-step explanation:

1/6 + 1/6 + 1/6 + 1/6 = 4/6. A unit fraction has a numerator of 1 so since 4 is the numerator in 4/6 You should add 1/6 four times.

Hope this helps!

Find the angle measure of b
Lilit [14]
13) b=145 because a line equals 180° so you subtract 35° from 180°
14) b=61 because it as right angle so 90 minus 29 equals 61
15) b= 23 because 360 is a full circle so you add 243 and 94 and get 337 then subtract 337 from 360
16)b=131 because you subtract 49 from 180
17) b=90 because you subtract 90 from 180
18) b=73 because of vertical angles

10&gt;29-3b Please help and explain your answer I will mark Brainlyest
Marta_Voda [28]
Step 1 , switch sides - 29-3b<10
step 2 , subtract 29 from both sides - -3b< -19
step 3 , multiply both sides by -1 - 3b > 19
step 4 (answer) - divide by 3 = 19/3
