Can someone please please answer this

10°

Step-by-step explanation:

You can see the three angles shown form a straight line, meaning they add up to 180°. We can et up the equation:

m<AOC + m<COD + m<DOB = 180°

And we can substitute the values we have:

5a + 18 + 24 - a + 8a - 30 = 180

Next, we can combine all like terms:

12a + 12 = 180

12a = 168

a = 14

Now, to find each angle, we can substitute the value of a:

m<AOC = 5a + 18 = 5(14) + 18 = 88°

m<COD = 24 - a = 24 - 14 = 10°

m<DOB = 8a - 30 = 8(14) - 30 = 82°

The smallest angle is <COD with a measure of 10°.

x+y=90

x=30-y=x
