Answer: AB=7.74in.;m<A
=57*;m<B=33*
Step-by-step explanation
this symbol means degrees *
A= 1/4E
B= 4E
C= E-4
D= E+4
A+B+C+D=100
25/4E=100
hence, E=16
10 squared + 13 squared = your answer squared.
So do that then take the square root of whatever you get.
2(2.2)(3.0) + 2(2.2)(7.5) + 2(7.5)(3.0)
13.2 33 45
Theres the work the answer is (4) 91.2
