Which of the following could be the side lengths of a triangle?
a. 12,15,30
b. 14,16,34
c. 15,16,33
d. 17, 18, 32

Here is your answer

D. 17, 18, 32

REASON:

Sum of any two sides of a triangle is always greater than the third side.

So,

17+18= 35

35>32

In other cases

a. 12+15= 27

27 <30

b. 14+16= 30

30 <34

c. 15+16= 31

31 <33

Hence other three can't be sides of a triangle.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
