Question

Tolong ya cepet teman teman no 4dan 5

Answer 1

4. 6x + 8x + 10x = 180
24x = 180
x = 7, 5 
a. TSR = PQT = 8x = 8 × 7, 5 = 60 
b. RTS = PTQ = 10x = 10 × 7, 5 = 75
c. TRS = QPR = 6x = 6 × 7,5 = 45
5. 5c + 7c = 180
12c = 180
c = 15
3c + y = 180
( 3 × 15 ) + y = 180
45 + y = 180
y = 180 - 45
y = 145
BCD = 135

Answer 2

No. 4
180 = 6x + 8x + 10x
180 = 24x
x = 7,5
sdt QPR = 6x = 6(7,5) = 45 drajat
sdt PQT = 8x = 8(7,5) = 60 drajat
sdt PTQ = 10x = 10(7,5) = 75 drajat
sdt TSR = 180 - sdt PQT = 180 - 60 = 120 drajat
sdt RTS = bertolak blkng dgn sdt PTQ = 75 drajat
sdt TRS = sdt QPR = 45 drajat

no. 5
180 = 7c + 5c
180 = 12c
c=15
-> sdt ABC = 3c = 3(15) = 45 drajat
-> sdt BCD = 180 - 45 = 135 drajat
