Can someone please help??

only B wrong

Step-by-step explanation:

sin0 =15/17 (1 quadrant)

sin0=Opposite/hypothenous

use pythagoras theorem,

adjadcent=√17²-15²

=√289-225

=√64

=8

cos0=Adjadcent/hypothenous

=8/17

sec0=1/cos0

=1/(8/17)

=17/8

cosec0=1/sin0

=1/(15/17)

=17/15

tan0=sin0/cos0

=(15/17)/(8/17)

=15/8

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
