Answer:
b) 11.7
Step-by-step explanation:
No Sari is incorrect because 120.78/9.9 is 12.2 and 12 is not greater than 12.2
Answer:70
Step-by-step explanation:
Answer:
x = 3
y = 6
Step-by-step explanation:
Apply the angle bisector theorem to find both variables.
Based on the theorem, we would have the following:
✔️x/2 = 6/4
Cross multiply
x*4 = 6*2
4x = 12
4x/4 = 12/4
x = 3
✔️9/y = 3/(8 - y)
Cross multiply
9(8 - y) = 3*y
72 - 9y = 3y
72 = 3y + 9y
72 = 12y
72/12 = 12y/12
6 = y
y = 6
(x+2) - (x-2) = 5. (x-2) (x+2) 6. (x+2)² - (x² - 2)² = 5. (x+2) (x-2) 6. (x² + 4x+4) - (x² - 4x + 4) = 5. x² - 4 6. (x² + 4x + 4 - x² + 4x - 4) = 5. x² - 4 6. 8x = 5.
