Answer:
x + 6x+10 + x+2 = 180
x = 21
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
x + 6x+10 + x+2 = 180
Combine like terms
8x + 12 = 180
Subtract 12 from each side
8x+12-12 = 180-12
8x =168
Divide each side by 8
8x/8 = 168/8
x =21
Answer:
Step-by-step explanation:
on what
P(y)=4/15
P(r)= 3/14
(I’m assuming this is without replacement since you are the starburst, so there is one less of the total.)
Three times the square of a number means 
Nine times a number is 
If these quantities must be equal, we have

We can divide both sides by 3 to get

Since x is non-zero, we can divide both sides by x:

1/21 would equal x. Hope this helps!
