Explanatory variable = independent variable = r
Answer:
x=15
Step-by-step explanation:
5x+(180-9x)+(180-8x)=180
total of a triangle angles is 180
5(x + 1) (3x - 8)
Hope this helps!
Let first number = x then
we have x and 9x and x + 100
x + 9x + x + 100 = 606
11x + 100 = 606
11x = 506
x = 46
so the three numbers are 46, 146 and 414 Answer
