Ответ:
We have this property of triangle:
sum of two sides > third side
Let us check for all options.
A.
7+7 >15
14>15
False
So option A is not correct.
B. 15, 7 , 9
15+7>9
22>9, true
7+9>15
16>15, true
15+9>7
24>7, true
So option B is correct.
C. 14, 6 ,7
14+6>7
20>7 , true
6+7>14
13>14, false
so option C is incorrect
D. 14, 6, 8
8+6 >14
14>14, false
So option D is incorrect.
Ответ:
B. Side = 15 cm, side = 7 cm, side = 9 cm
I took the test too! and got it right, so for sure you will get it right too.
