Thats is how you do it and its the answer.
Answer: FALSE .

For two (2) angles to be supplementary, they must add up to 180° ;
and the two angles given — 98° and 72° — add up to 170°.
{Note: 98 + 72 = 170 — NOT "180" ; and as such are NOT supplementary.}.

To change degrees to radian we have to use a rule :
Rad=degree/180/π
Rad = 55/180/π
Final answer:
Rad= (11/36)π [this answer is In pi]
Rad= 0.96 [this answers is the simplified version]
