Tolong dijawab no 7 yaa!!!!

Jumlah seluruh sudut = 360°
maka
360 = 65 + 90 + 3x + 2x
360 = 155 + 5x
-5x = 155 - 360
-5x = -205
x = -205 : -5
x = 41

Sudut BOD = 65 + 2x = 65 + (2×41) = 65 + 82 = 147°

semoga membantu^^

Sudut

360=65+90+2x+3x
360=155+5x
360-155=5x
205=5x
205/5=x
41=x
<BOD=65+2x
<BOD=65+2(41)
<BOD=65+82
<BOD=147 Derajat
