Connexus: C,D,C,A,A.
Step-by-step explanation:

<u>Given expression is </u>

can be rewritten as

We know,

And

So, using this identity, we


can be further rewritten as





<u>Hence, </u>

Linear pair angles have too add to 180, so
5x+9+3x+11=180
8x+20=180
8x=160
x=20
so angle S is 5*20+9 = 109
angle T is 3*20+11 = 71
