Question

Tolong dong teman saya lagi perlu banget nih buat besok ya
no. 5 dan 6 doang .

Answer 1

5. sudut A + sudut D = 180
5x - 38 + 2x + 15 = 180
7x - 23 = 180
7x = 203
x = 29

sdut D = sudut B
sudut B = 2x + 15
sudut B = 73

Answer 2

5.
dari  sudut pada jajar genjang
- sudut yg berhadapan sama besar, jadi < B = < D
- sudut yg salaing berdekatan jumlahnya 180
 < A + < D = 180
5x - 38 + 2x + 15 = 180
7x = 180 + 38 - 15
7x = 203
x = 29
< B = 2x + 15 = 2(29) + 15 = 73 (C)

6.
< K + < L = 180
2a + 3a = 180
5a = 180
a = 36

< K = 2a = 2 ( 36) = 72
< L = 3a = 3 ( 36) = 108

< L = < N
108 = 7y + 3
108 - 3 = 7y
105 = 7y
y = 15

< K = < M
72 = 5x + 2
72 - 2 = 5x
70 = 5x
x = 14

jadi x + y = 14 + 15 = 29(D)
