You know that the sum of the interior angles in a triangle is 180
we will add all the angles,
(x+8)+(2x-8)+(3x-12)=180
x+8+2x-8+3x-12=180 8 and -8 cancel out
6x-12=180
6x=180+12
6x=192
x=192/6=32
x=32
Answer: 1. is 50 2. is 111 3. is 26 4. is 45 and 5. is 51
Step-by-step explanation: The formula for Pythagorean theorem is A^2 plus B^2 = c^2
Sry that took so long did it wrong at first
2/3 (simply simplify/divide them by 3)
Or
.66666 (basically repeating numbers)
Or
66.6 % (Make sure for the decimal or percentage you write a line above the 6 after the 1st number behind the decimal to show it as a repeating number!)
Answer:
this is not the answer but it might help you find the answer
Step-by-step explanation:
The area of a regular decagon can be calculated using the formula for finding the area of a general regular polygon. Area of a Regular Polygon = 12 x Perimeter x Apothem. The diagram of a regular decagon ABCDEFGHIJ is given above.
50(30%) = 15
50 - 15 = 35
35 (6%) = 2.1
35 + 2.1 = $37.10
the total cost of his order is $37.10 !!
