A) About 9.1
B) about 14.1
C) about 17.2
D) about 18.1

Please help me

D. 18.1

K^+H^+G^=180° (sum of int angles of triangle)

K^+30+62=180

K^=88°

GH/sinK=KG/sinH

X/sin88=16/sin62

X*sin62/sin62=16*sin88/sin62

X=18.1

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
