Answer:
221
Step-by-step explanation:
13 x 17 = 221
Answer:
86°
Step-by-step explanation:
b = 29× 2 = 58
d= [180-(86+29)]×2 = 130
a=c=x
a+b+c+d = 360
2x+188= 360
2x= 172
x= 86
a = c = 86°
Total units would be: 3+4 = 7
value of 1 unit = 28/7 = 4
ratio would be 3(4) & 4(4) = 12 & 16
It will take 52 hours they will go 416 miles
