Answer:

1. ∠A and ∠B are right angles.                      Given

2. m∠A = m∠ B                                               All right angles are congruent.

3. ∠BEC≅ ∠AED                                              Vertical angles are congruent

4. ΔCBE ~ ΔDAE                                               AA

Step-by-step explanation:

A proof always begins with the givens.

1. ∠A and ∠B are right angles. -------------->Given

2. m∠A = m∠ B  are equal since----------->  All right angles are congruent.

3. ∠BEC≅ ∠AED  are also equal since---->Vertical angles are congruent

4. ΔCBE ~ ΔDAE since two angles are equal----------> AA

Condense the log equation: 4 log x + log y - 5 log z
Setler [38]

Answer:

The condensed log equation is: \log{\frac{x^4y}{z^5}}

Step-by-step explanation:

We use these following logarithm properties to solve this question:

a\log{x} = \log{x^a}

\log{a} + \log{b} = \log{ab}

\log{a} - \log{b} = \log{\frac{a}{b}}

In this question:

4\log{x} = \log{x^4}

5\log{5} = \log{z^5}

So

4\log{x} + \log{y} - 5\log{z}

Becomes:

\log{x^4} + \log{y} - \log{z^5}

Now applying the addition and subtraction properties, we have:

\log{\frac{x^4y}{z^5}}

The condensed log equation is: \log{\frac{x^4y}{z^5}}
