Answer:
x=1
Step-by-step explanation:
slope AB = (7-5) / (3 - -1) = 2 / 4 = 1/2
slope CD = (23-11) / (x-7) = 12 / (x-7)
12 / (x-7) = - 2 ... perpendicular to AB slope 1 = - 1/slope 2
-2 (x-7) = 12
-2x + 14 = 12
-2x = -2
x = 1
Answer:
19.64°
Step-by-step explanation:
The angle of elevation can be calculated as follows
Tan ©= 15/42
= 0.357
= tan-1 0.357
= 19.64°
Hence the angle of elevation is 19.64°
Answer:
Discount % = (Discount/List Price) × 100
Step-by-step explanation:
To calculate the discount, you must have the list price (marked price) and the selling price of the product you are buying.
Example: If the list price of a book is $50, and $10 discount is offered on the book, then the discount percentage is calculated as follows.
Discount % = (Discount/List Price) × 100
List price = $50; discount = $10
Discount (%) = (10/50) × 100
= 100/5
= 20%
