vagabundo [1.1K]

For this case we must find the quotient of the following expression:

\frac {(- 8x ^ 2 * y) (- 7x ^ 5 * y ^ 3)} {- 2x ^ 2 * y ^ 3}

We can rewrite the expression as:

(We take into account that- * - = +)

\frac {56x ^ 2 * y * x ^ 5 * y ^ 3} {- 2x ^ 2 * y ^ 3} =

By definition of multiplication of powers of the same base, we place the same base and add the exponents:

\frac {56x ^ {2 + 5} * y ^ {1 + 3}} {- 2x ^ 2 * y ^ 3} =\\\frac {56x ^ {7} * y ^ {4}} {- 2x ^ 2 * y ^ 3} =

By definition of division of powers of the same base, we place the same base and subtract the exponents:

-28x^{ 7-2} * y^{ 4-3} =\\-28x ^ 5 * y

Answer:

-28x ^ 5 * y

AURORKA [14]
Short Answer: 150

Remark
You have to use two facts.
1. The central angle = 2 * the angle at B
2. The central angle = the arc angle.

Given
angle at B = 75 degrees.

Calculate the central angle
Central angle = 2 * angle at B
Central angle = 2 * 75
Central angle = 150

Conclusion
The arc angle = Central angle
The arc angle = 150 degrees.
