152
Step-by-step explanation:
360-(118+54)
L = 0 bcause it cancels itself out
Answer:
check: 50+160+130+20 = 360
50:160 = 5 : 16
Step-by-step explanation:et the smaller of the unknown angles be 5x and the larger of the two be 16x
so 130+20+5x+16x = 360
21x = 210
x = 10
so the two missing angles are 50° and 160°
check: 50+160+130+20 = 360
50:160 = 5 : 16
