Question

In ∆RST, /_ S = 90°, /_ T = 30°
RT = 12 cm, Find RS and ST.​

Answer 1

Answer:

for answer see the attachment

Answer 2

angle r = r+s +t = 180°

r+30°+90=180°

120°+r =180°

r = 180° -120°

r=60°

rs and St = by P.G.T

LET rs be x

and St be x

by P.G.T

(rs )²+ (St )²=(RT)

2x+2x=12

4x=12

x=12\4

x=3

so rs =3 and st = 3
