1/2 - 5/13 = 3/26 = 0.115
Because: 1/2 - 5/13 = 1 x 13 ÷ 2 x 13 - 5 x 2 ÷ 13 x 2 = 13/26 - 10/26
13/26 - 10/26 = 13 - 10 ÷26 = 3/26 or 0.115.

Complementary angles add up to 90 degrees.
So to find A you would need to add A and B together and equal it to 90 (3x+25+5x-7=90)
Combine like terms together (8x+18=90)
Subtract 18 from night sides (8x=72)
Divide by 8 on both sides (x=9)
Then to find A substitute x into its equation (3(9)+25)=(27+25)=52
A=52 I think
Remember, ab+ac=a(b+c)
undistribute the 14
14(l)+14(3a)=14(l+3a)
