Answers:
L = 4
M = -3

--------------------------------------

Explanation:

On the left side, the number 20-12i is in the form a+bi where a = 20 and b = -12

On the right side, 5L+(4M)i is in the form a+bi where a = 5L and b = 4M

Equating the real parts a = 20 and a = 5L has us get
5L = 20
5L/5 = 20/5
L = 4

Do the same with the imaginary parts as well
b = -12
b = 4M
4M = -12
4M/4 = -12/4
M = -3

Find tan of 45 degrees
Arturiano [62]

Answer:

tan(45°) = 1

Step-by-step explanation:

We know that sin (45°) = √2/2, and cos(45°) = √2/2.

Given that tan(x) = sen(x) / cos(x), we get:

tan(45°) = (√2/2) / (√2/2) = 1

Therefore, tan(45°) = 1

Pleasee Help!!! v2=?
adoni [48]
<h3>Given :</h3>

  • \sf l = p(v_{2} - v_{1})

<h3>To Find :</h3>

  • \tt v_{2} = ?

<h3>Solution :</h3>

\sf \dashrightarrow l = p(v_{2} - v_{1})

\sf \dashrightarrow \dfrac{l}{p} = v_{2} - v_{1}

\sf \dashrightarrow \dfrac{l}{p} + v_{1} = v_{2}

\sf \dashrightarrow v_{2} = \dfrac{l}{p} + v_{1}

\large \underline{\boxed{\bf{v_{2} = \dfrac{l}{p} + v_{1}}}}

Hence, value of \sf v_{2} = \dfrac{l}{p} + v_{1}
