Tolong kerjakan nomor 1 sampai 5 yg baik tolong ya :)

1.2(3x-25) + 2 (x+5) = 360
6x-50+2x+10=360
8x = 360 +40
8x = 400
x = 50°
<L = <N
= 3x-25
= 3.50 -25
= 125°

2.L.j=(panjang.tinggi)/2
=(12.3)/2
= 18
L.l= (d1+d2)/2
= (10.8)/2
= 40
jd.total luasnya 18+40 = 58
(gk ada ket.satuan)

3.gk tau

4.(a+b).t /2
(10+15).12 /2
150 cm^2

5.L.bk = Lp
d1.d2/2 = s.s
8.d2/2 = 10.10
8.d2/2 = 100
d2 = (100.2)/8
d2 = 200/8
d2 = 25 cm

semoga membantu,maaf nomer 3 gk tau
