Berapa Nilai x+y= tolong bantu ya

LPSR = LPRS = 64 °
4y + 64° + 64° = 180°
4y + 128° = 180°
4y = 180° - 128°
4y = 52°
y= 52/4 = 13°

LPRQ = 180° - 64= = 116°

4x + 4x + 116° = 180°
8x + 116° = 180°
8x = 180° - 116°
8x = 64°
x = 64/8
x = 8°

x + y = 8° + 13 ° = 21°

A. 21

sudut PSR + sudut SRP + sudut SPR = 180
= 64 + 64 + 4 y = 180
4y = 180 - 128
4y =52
y= 52/4 =13

besar sudut PRQ
= 180 - (64)
=116

4x = 180 - 116 / 2
     =64/2
4x =32
x= 32 / 4 =8


maka,besar x + y  adalah
=8 + 13
=21
