Compute the value of S

Step-by-step explanation:
sum of all angles of triangle are 180°
therefore,
angle,
P + T + S = 180°
P = 90° , T = 36° ( given )
so,
→ 90 + 36 + S = 180
→ 126 + S = 180
→ S = 180 - 126 = 54°
→ S = 54°
therefore, S is 54° so, option D is correct.
hope this answer helps you dear...take care and may u have a great day ahead and! also ur exam/test goes well!
