50
Step-by-step explanation:
Since AE is the bisector of angle BAC,so angle BAE and Angle CAE is equal. Here Angle CAE and Angle EAC is same.
therefore,
m(Angle BAE)=m(Angle EAC)

or, 2x=40
or, x=20
Hence,
m(Angle EAC)=

=

Mrs. Yin bought more turkey than chicken. I know because 0.80 is greater than 0.69
Answer:
Some relationships:
Angle FGH + Angle FHG = 90
sin(FGH) = cos(FHG)
cos(FGH) = sin(FHG)
Increase = 15.96 - 13.30
Increase = 2.66
percentage of the increase = 2.66/13.30 x 100 = 20%
I did a quick search and the web said there are 12 categories! So none of the choices...
"Excel groups functions into 12 categories: Compatibility, Cube, Database, Date and Time, Engineering,Financial, Information, Logical, Lookup & Reference, Math & Trigonometry, Statistical and Text."
There's one other category called "Web functions", mentioned in Microsoft's website.
So the answer is 13.
