Answer:
Step-by-step explanation:
The acute angles in a right triangle are complementary:
   2x° +(x -6)° = 90°
   3x = 96 . . . . . . . . . divide by °, add 6
   x = 32 . . . . . . . . . divide by 3
   (x-6)° = (32 -6)° = 26°
   2x° = 2(32)° = 64°
The acute angles have measures 26° and 64°.
 
        
             
        
        
        
4x-10=18
4x=18+10
4x=28
x=28/4

Answer: 345.4
Step-by-step explanation:
SA=2πr^2+2πrh
SA=2(3.14)(5)^2+2(3.14)(5)(6)
SA=2(3.14)(25)+2(3.14)(30)
SA=2(78.5)+2(94.2)
SA=157+188.4
SA=345.4
