Answer:
b = 87°
Step-by-step explanation:
In order to answer this question, we need to utilise an important angle fact which is <em>angles in a quadrilateral add up to 360° </em>
Using the information we can set up an equation to find the value of b
→ Form equation
63 + 140 + 70 + b = 360
→ Simplify
273 + b = 360
→ Minus 273 from both sides isolate b
b = 87°
X/3=1351/7
cross multiply
7x=4053
divide by seven on both sides
x=579
Answer:
C)
Step-by-step explanation:
Every 
is 6 times bigger than 
Step-by-step explanation:
9.1k=64.7
Find k
64.7/9.1=7
Plug in 7
9.1(7)=64.7
Multiply 9.1 and 7=63.7
63.7=64.7
Divide
1.02 or 1 1/50
