Question

In the figure find a + b

Answer 1

Answer:

Step-by-step explanation:

(x+9)+5(x/2-1)+1/2x=180                                  (∴LP)

x+9+5x/2-5+1/2x=180

x+5x+1/2x+9-5=180

11x/2+4=180

11x/2=176

11x=176*2

11x=352

x=352/11

x=32

now

x+9=32+9

     =41

so,

a+b=180-(x+9)

     =180-41

     =139
