Question

Tolong nomor 5 dan 6

Answer 1

NO.5 A=90 B=45 C=45 D=90
NO.6 X=45 Y=90 Z=145  (KALAU GAK SALAH)

Answer 2

5. a = 90°
b = 180 - (e + a) = 180 - 125 = 55
c = 90 - b = 90 - 55 = 35
d = 90
e = 180 - (a + 55) = 180 - 145 = 35

6. 30 + y + 40 = 180
70 + y = 180
y = 110

40 + z = 180        z + x = 180
z = 140                140 + x = 180,  x = 40
