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

Answer:
Step-by-step explanation:
6x-2(9x-19)=26
6x -18x +38 =26
-12x = 26-38
-12x = -12
x=1
Step-by-step explanation:
The formula to find the circumference is
C=d×(3.14)
Therefore you must work backwards to find the radius.
If the circumference is x then divide both sides of the equation by pie to get the diameter. Then once you have the diameter you divide that number by two to get the radius.
-2x - 2
Step-by-step explanation:
you would just have to plug in the 4 and -3 into the equation.
