What is the quotient of numerical answers expected!

 " 0.4 " .

Step-by-step explanation:

"" = " 2 ÷ 5 " =  0.4  .  {Use calculator). _____________________________________________

Or:  "" = "" ;

                                          =  ""  ;                                            

                                          =  " 4 ÷ 10 " =  " { 4  ÷  10 } "  =  0.4 . _____________________________________________

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
