Answer:
D. 29 cm.
Step-by-step explanation:
The measure of the longest side cannot be equal or greater than (17 + 13) = 30 cm or it wouldn't be a triangle.
So it cannot be 30 or 31 cm long. Also as we want the longest side so it can't be 4 cm.
The answer is 29 cm.
heyyyyyyyy i didddddddddddddddddd
12
x = k/y Multiply each side by y
k = xy Insert values
= 6 × 72
= 432
x = 432/y Let y = 36
= 432/36
x = 12
