Triangle has 3 angles, A, B, C. The total interior angle of a triangle is 180.
180 = A + B + C
180 = 72 + B + 113
180 = B + 185
B = 180 - 185
B = -5
This only proves that the figure is not a triangle because angle B is negative.
Can you make the a bit more clear
84 pounds on earth is about 14 pounds on the moon but to be exact it is 13.89 pounds.
Answer:
Q1
|a-b| = b-a when a<b
Q2
104159/33000
Step-by-step explanation:
Q1
If a<b then a-b will always be negative. To get the absolute value, we can take -(a-b) = -a+b = b-a.
Q2
Let x = 3.12789789789...
We isolate the repeating decimal to start after the decimal, so we multiply by 100.
100x = 312.789789789...
We want to multiply by 10 for each digit that repeats (in this case 3), to get the repeating part to the left of the decimal.
100000x = 312789.789789
Subtracting the two...
x(100000-100) = 312789.789789 - 312.789789
99900x = 312477
x = 312477/99000 = 104159/33000
