If tan(tita) = 2 then find the values of other trigonometric ratios.​
Nady [450]
<h2>Answer:</h2>

<u>We know that</u>,

sec²θ = 1 + tan²θ

⇒ sec²θ = 1 + (2)²

⇒ sec²θ = 5

⇒ secθ = √5 …[1]

<u>Also</u>,

⇒ cosθ = 1/secθ

⇒ cosθ = 1/√5 …[2]

<u>Now, using</u>

tanθ = sinθ/cosθ

⇒2 = sinθ/1/√5

⇒2 = sinθ√5

⇒sinθ = 2/√5 …[3]

<u>Also</u>,

cosecθ = 1/sinθ

⇒cosecθ = √5/2 …[4]

cotθ = 1/tanθ

⇒cotθ = 1/2 ….[5]

LM=9, NR=16, SR=8. Find the perimeter of △SMP.
Amanda [17]

Answer:

<h2>perimeter of △SMP = 25</h2>

Step-by-step explanation:

The perimeter of the triangle △SMP is the sum of al the sides of the triangle.

Perimeter of △SMP = ||MS|| + ||MP|| + ||SP||

Note that the triangle △LRN, △LSM, △MPN and △SRP are all scalene triangles showing that their sides are different.

Given LM=9, NR=16 and SR=8

NR = NP+PR

Since NP = PR

NR = NP+NP

NR =2NP

NP = NR/2 = 16/2

NP = 8

From △LSM,  NP = PR = <u>MS</u><u> = 8</u>

Also since LM = MN, MN = 9

From △SRP, SR = RP = <u>PS =  9</u>

Also SR =<u> MP = 8</u>

From the equation above, perimeter of △SMP = ||MS|| + ||MP|| + ||SP||

perimeter of △SMP = 8+8+9

perimeter of △SMP = 25

Step-by-step explanation:

The denominator is the bottom number, and represents how many parts are possible—in other words, how many parts go into a whole. The numerator is the top number, and represents how many parts you have.

\frac{Numerator}{Denominator}
