Answer:
x = 5 y = 9
Step-by-step explanation:
B= 20°
and c = 160°
b is equal to the given angle, b = 20°
c is 180 - 20 = 160°
This can be solved using a ratio. The ratio is: 13/20=x/60 this would then become 20x= 780 divide both sides by 20 and you get x=39. the answer is 39
Answer:
20
Step-by-step explanation:
7 x 4 = 28
so you do 5 x 4 and get 20
Answer:
5/16
