Answer:
45 độ
Step-by-step explanation:
SA vuông góc (ABC) => góc SAB = 90 độ; góc giữa SB và mặt phẳng đáy = góc SBA
SA=AB=a => SAB là tam giác cân
KL: góc giữa SB và mặt phẳng đáy SBA = 45 độ
We know that the midpoint is the a point in the center of the line. This means that from the midpoint to the endpoint is half the length of the overall line. This means that 11 units is half the length of the line. Two halves make a whole so 2 × 11 = 22 units as the length of the entire line!
Hope this helps!

For Britney
Answer: the total price of the trip is
$1087.5
Step-by-step explanation:
The trip costs $1450 and they have a special discount of 35% off. It means that the amount that would be taken off is
35/100 × 1450 = $507.5
The cost of the trip would be
1450 - 507.5 = $942.5
The tax rate for the package is 10%. It means that the amount of tax to be paid is
10/100 × 1450 = $145
Therefore, the total price of the trip would be
942.5 + 145 = $1087.5
