Answer and Step-by-step explanation:
Hello person who looks like Tommyinnit!
The triangle we have here is an Isosceles Triangle.
We can tell because we see that there are two red marks, one on side NO and one on side NM, which means that the sides are equal to each other.
With that being said, this means that angle M is also 3y - 12.
To solve for y, we would add all the angles up and equal it to 180.
180 = 6y + 3y + 3y - 12 - 12
Combine like terms.
180 = 12y - 24
Add 24 to both sides.
204 = 12y
Divide by 12 to each side.
17 = y
Now we know 17 is equal to y, we plug it in for angle O.
3(17) - 12 = 51 - 12 = 39
The measure of angle O is 39 degrees.
