C= 6.7
A^2 + B^2 = C^2
6^2 + 3^2 = C^2
36+9 = 45
Square root 45 = 6.7
Answer:
The angles in the triangle and 10, 80 and 90
Step-by-step explanation:
The two angles that are left in a right triangle add to 90 degrees
8:1 means that there total is 9
8x+1x = 9x
9x = 90
Divide by 9
9x/9 = 90/9
x = 10
8*10 = 80
1*10 = 10
The angles are 80 and 10
The angles in the triangle and 10, 80 and 90
Factoring completely you get: 3(3x-1)(2x+3)
Answer:
Around 25 pages / 1.5 minute(s)
Step-by-step explanation:
18 / 12 = 1.5 minutes per paper.
So, 18 + 18 = 36 + 1 = 37 minutes
12 + 12 = 24 + 1 = 25
37 / 25 = 1.5
