N-the number
the product of 8 and the number: 8 × n = 8n
5 less than the 8n: <u>8n - 5</u>
It doesn’t have a value. The absolute value function is always positive or 0
Answer:
x=70°
y=30°
z=20°
Step-by-step explanation:
You first need to find y, which would be 30 because the sum of the first two angles is 150, and a triangle has 180 degrees, so 180-150=30.
By finding y, we can now find a, because if you take the entire triangle, y+z must equal 50. So, z=20 because 30+z=50.
And finally, we can find x to be 70 since the sum of the two other angles is 110 and 180-110=70.
I think you're right. I'm in pre-algebra, and sucks at it. Yet, I keep a A.
