Answer:
£124
Step-by-step explanation:
first of all, you're meant to add all the figures given on the pie chart, which is 29+137+58+62+74 and that will give you a total of 360 degrees 
so, you say 360 degrees is equal to the total amount of money he spent, which is £720, what about 62 degrees 
therefore, you just do (62×720)÷360
that will give you £124
 
        
             
        
        
        
Answer:
x=8
Step-by-step explanation:
Triangle DCE is similar to EGF
CE/EF=DE/EG
Substitute
(8x-1)/21=(6x+3)/17
Cross multiply 
(8x−1)*(17)=(6x+3)*(21)
136x−17=126x+63
Subtract 126x from both sides
10x−17=63
Add 17 to both sides.
10x−17+17=63+17
10x=80
Divide both sides by 10.
x=8
 
        
             
        
        
        
2π radians is equal to 360° which is just π rad/180° so:
120°(π/180°)=2π/3
