Answer:
The length of side AB is 5 units
Step-by-step explanation:
* Lets revise how to find the distance between two points
- If there are two points their coordinates are (x1 , y1) and (x2 , y2),
then we can find the distance between them by this rule:
d = √[(x2 - x1)² + (y2 - y1)²]
- Now lets solve the problem
∵ A = (4 , -5)
∵ B = (7 , -9)
- To find the length of AB use the rule of the distance above
- Let point A is (x1 , y1) and point B is (x2 , y2)
∵ x1 = 4 and x2 = 7
∵ y1 = -5 and y2 = -9
∴ AB = √[(7 - 4)² + (-9 - -5)²]
∴ AB = √[(3)² + (-4)²]
∴ AB = √[9 + 16] = √25 = 5
* The length of side AB is 5 units
Answer:
Angle #1 is 45 degrees
Angle #2 is 60 degrees
Angle #3 is 75 degrees
Step-by-step explanation:
x- angle #1
y- angle #2
(180-x-y)- angle #3
3x=180-x
4x=180
x=45
180-x-y=y+15
y=60
180-60-45=
180-105= 75
Answer:
$77.76
Step-by-step explanation:
80x0.10=72
72x 0.08= 5.76
72+5.76 = 77.76
Answer:
$98,048.77
Step-by-step explanation:
First you want to find out how much he has put in without interest so you would do 237.95*12 to figure out how much he puts in per year then times that number by 30 to figure out how much he has put in in total, after this you subtract this total from the 183,710.77 to get the total amount of interest
