The numbers are 15 and 105.
Lin thought a two digit number that is 15, if we multiply 15 with 7 , 15 x 7 = 105 that is we get Jen's number.
and if we put 0 between the two digits of Lin's number, we also get Jen's number;
that is 105.
you do 0.047×40 and what ever that gives you you add it to 40 and it will give you the answer
Answer:
C. 37.8 units
Step-by-step explanation:
ED = 17/ cos(38°) = 17 / 0.7880 = 21.6 units
DF = 17× tan (38°) = 17× 0.7813 = 13.3 units
CD = 10/13.3 × 21.6 = 16.2 units
so, the length of CE = 21.6+16.2 = 37.8 units
