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
2x^-3= 2/x^3
you can't multiple 2x to the power of -3 because is not correct. so you need to change the equation for it to give you an answer
Answer:A quadrilateral always has a sum of 360o in total.
5/4, 1.3, 1 8/25 is ur answer
To find 29/9 as a mixed number you need to find out how many times does 9 fit in 29
9
18
27
36
We see that it fits 3 time 3 is your whole #
We also see that 29 - 27 = 3 so you write like this:
3 3/9
The denominator of the original fraction does change
