Step-by-step explanation:
1,303 ÷ 13= 100 3/13
Ответ:
The correct answer is B.
Step-by-step explanation:
In order to determine if three given lengths can be the sides of a triangle, we should use the triangle inequality. Recall that the triangle inequality tell us that the sum of any two sides of a triangle is larger that the third side.
Then, we must try all possible sums of two lengths and compare with the other one. So,
7 + 8 = 15 > 13,7 + 13 = 20 > 8,8 + 13 = 21 > 7.As the triangle inequality holds, we can affirm that it is a triangle. Then, we eliminate D. Moreover, it cannot be a right triangle because Pythagoras theorem does not hold and 7²+8²=113 < 13²=169, then the triangle is obtuse.
