Question

Tolong yah no 25-26............

Answer 1

25
nilai c = 180 - 35 - 70 = 75
nilai d = 180 - 75 = 105
nilai p = nilai r =  70 ( sdt dalam berseberangan)
p + d = 70 + 105 = 175 (C)

26
PQ =
       = √400
       = 20

keliling = 40 + 21 + 29 = 70 (C)

Answer 2

25.Sudut c=180-35-70=75
    Sudut d=180-75=105
    Sudut p=sudut r=70 dalam bersebrangan 
    Sudut p+ sudut d=70+105=175 (C)
26.pythagoras=29²-21²
                    =841-441
                    =√400=20
maka,keliling segitiga=a+b+c
                              =21+20+29
                              =70 (C)
SEMOGA MEMBANTU YA
