First, you have to imagine that you cut the upper triangle. If you do that, then this is how the inner angles are added to 180°:
180° = 90° + (x/2) + (7x - 90°)
180° = x/2 + 7x
180° = x *(1/2 + 7)
180° = x*(15/2)
2/15 * 180° = x
24 = x
Angle A:
A= x/2
A = 24/2
A = 12°
Angle B:
B = 7x
B = 7*24
B = 168°
The two bottom angles are both worth 90°.
Answer:
x² - 6x + 9
Step-by-step explanation:
(x - 3)² = x² - 6x + 9
B is correct the devotion is only 2 compared to 4.
A is wrong because variate A has higher trees then variate B
C is wrong because deviation for A is 4 compared to 2 ( opposite of B)
D is wrong because 4th one is 10 for A and 13 for B. 10 is not greater than 13
Answer:
$12.96
Step-by-step explanation:
determine what the decimal form of 8% is
⇒ 8% = 0.08
multiply $12 by 0.08
⇒ $12 x 0.08
⇒ $0.96
add $0.96 to $12
⇒ $12 + $0.96
⇒ $12.96
new price
⇒ $12.96
