1.) 72 degrees
one straight line=180 degrees
so
2x+3x=180
5x=180
x=36
then since you need angle of ABC, if you look, ABC is 2x and we solved that x is 36 so 2x=2(36)=72
2.) 52 degrees
honestly this is a trick question but if you look closely, angle EFG is in a 90 degree angle with GFH. So literally all you have to do is 90-38= 52
Area = length * width
(10x + 6)(9x + 8)
Multiple (I used rainbow method)
10x * 9x = 90x^2
10x * 8 = 80x
6 * 9x = 54x
6 * 8 = 48
90x^2 + 80x + 54x + 48
90x^2+ 134x + 48
The area is 90x^2 + 134x + 48
