Answer 1

Answer:

Step-by-step explanation:

3x+7+2x-9+x=180

6x-2=180

X =182/6

Answer 2

Step-by-step explanation:

We know that the sum of all the adjacent angles of a present over a straight line is 180°

Therefore,

According to the question,

<AOC + <COD + <DOB = 180°

=) 3x°+7°+2x°–9°+x°=180°

=) 6x°=180°–7°+9°

=)6x°=182°

=)x°=

$\frac{182}{6}$

Now,

<AOC= (3*182/6+7)°

=(91+7)°

=98°

<COD=(2*182/6–9)

=(182/3–9)°

$51 \frac{2}{3}$

<DOB=

$\frac{182}{6} \\ = 30 \frac{1}{3}$
