tolong bantu yang no. 23 sama 24 plizzz besok dikumpulin!!!

23.
DOC + DOB = 90°
(4x + 6) + (7x - 4) = 90°
11x + 2 = 90
11x = 90 - 2
11x = 88
x = 8
AOC = AOD + DOC
AOC = 90 + (4x + 6)
AOC = 4x + 96
AOC = 4 x 8 + 96
AOC = 32 + 96
AOC = 128 (Jawabanya B)

24. ABC - ABD = CBD
180 - (9x + 25) = CBD
CBD = 155 - 9x
EDC + BDC = EDB
(8x - 11) + BDC = 180
BDC = 180 - (8x - 11)
BDC = 191 - 8x
CBD + BDC + DCB = 180
(155 - 9x) + (191 - 8x) + 38 = 180
384 - 17x = 180
-17x = 180 - 384
-17x = -204
17x = 204
x = 204 : 17
x = 12
CBD = 155 - 9x
CBD = 155 - 9 x 12
CBD = 155 - 108
CBD = 47 (Jawabanya B)

Terimakasih

#23
(4x + 6) + (7x - 4) = 90°
4x + 7x = 90° - 6 + 4
11x = 88°
x = 88/11
x = 8°

AOC = 90° + (4x + 6)
AOC = 90° + 38°
AOC = 128°

#24
(180 - (8x - 11)) + (180 - (9x + 25)) + 38 = 180
180 - 11 + 180 + 25 + 38 - 180 = 8x + 9x
232 = 17x
x = 13,64°
