If you look closely the area where 3x is congruent to the other side of the 90 degree angle with one part as 0.5x + 34

So
3x + 0.5x + 34= 90

x will be 16

So plug it in

0.5(16) + 34= 42 degrees

And

3(16)= 48 degrees

That left half of the circle is 180 degrees and since we know the angle 3x is 48 degrees we subtract it from 180 to get angle AE

180-48

132 degrees is your answer

Write 3a^2 b^2 c^5 / 8x^4 y^3 z using no denominator

pantera1 [17]

Currently the denominator is $8x^4y^3z$ . If you want to move those up so they sit with the numerator, then what you have to do is make the exponents negative. You make a negative exponent positive by moving it under a 1; undo that process to make the exponents negative. If we do that, then the expression would be $3a^2b^2c^58 ^{-1} x ^{-4} y ^{-3} z ^{-1}$
