Well a triangle equals 180 degrees so if you already have 90 then you would need the other 90. By looking at the triangle I would say y=45. I hope I helped! :)
Answer:
Step-by-step explanation:
The total number of workers is our unknown. If 40% of this unknown number are women and the number of women is 1380, then the equation looks like this:
(remember that the word "of" generally means to multiply)
(also remember that we have to use the decimal form of a percent in an equation)
.40(x) = 1380 then divide to get the number of total workers:
x = 3450
80 * 70 percent = cookies sold
80 * .7 = cookies sold
56 = cookies sold
Ok so in order to find the answer to this problem we are going to Multiply

and

.
If 1.5cm = 4ft
1.5÷4 =0.375
0.375cm= 1ft
16×0.375=6
12×0.375=4.5
hopefully this is correct and helped! ♡
