Answer:
The answer is 20812
The numeral system we use is a base ten numeral system. Base ten numeral numbers are: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
The number has:
2 "tens thousands" = 2 * 10000 = 20000
0 "thousands" = 0
8 "hundreds " = 8 * 100 = 800
1 "tens" = 1 * 10 = 10
2 "ones" = 2 * 1 = 2
Sum all the results => 20000+800+10+2 = 20812
That is how you write a number using base ten numerals (numbers from 0 to 9)
180 - 30 = 150or triangle is isoscele so each base angle is 150 / 2 = 75
The correct answer is 800 pounds
Every triangle is equal to 180 degrees so u need to subtract what is already shown form 180,, 180-120=60 and then 60-40 20 so the final degree is 20 ,,,,, to check u can add them all together if if they equal 180 u should be g
