Answer:

Step-by-step explanation:

use the distributive property first; distribute 4 TO a+2

4(a+2) = 4a+8

once you have got your answer, make the new equation

4a + 8= - 4

Now, solve the equation

4a + 8= - 4

4a = -4-8

4a = -12

a = -12/4   ( always remember to put the sign )

a = -3

What is the m∠N ? Can someone help me :)
Sauron [17]

Answer:

<h2>61°</h2>

Step-by-step explanation:

Use the sine law:

\dfrac{MO}{\sin(\angle N)}=\dfrac{NM}{\sin(\angle O)}

We have:

MO=18\\\\NM=6\\\\m\angle O=17^o\to\sin17^o\approx0.2924

Substitute:

\dfrac{18}{\sin(\angle N)}=\dfrac{6}{0.2924}         <em>cross multiply</em>

6\sin(\angle N)=(18)(0.2924)

6\sin(\angle N)=5.2632          <em>divide both sides by 6</em>

\sin(\angle N)=0.8772\to m\angle N\approx61^o
