Which of the following pairs of angles is not necessarily congruent

Alex

Answer:

E. $\angle 3$ and $\angle 5$ .

Explanation:

According to the figure, we have the following conclusions:

1) $\angle 1$ and $\angle 2$ are vertical opposite angles. ( $m \angle 1 = m \angle 2$ )

2) $\angle 2$ and $\angle 3$ are internal alternate angles. ( $m \angle 2 = m\angle 3$ )

3) $\angle 2$ and $\angle 4$ are corresponding angles. ( $m\angle 2 = m\angle 4$ )

4) $\angle 3$ and $\angle 4$ are vertical opposite angles. ( $m \angle 3 = m \angle 4$ )

But, $\angle 3$ and $\angle 5$ , since $m \angle 3 + m\angle 6 + m\angle 5 = 180^{\circ}$ , where $\angle 3$ is an acute angle and $\angle 6$ is a right angle, and $m \angle 4 + m \angle 5 = 90^{\circ}$ . Then,

$m\angle 5 = 90^{\circ} -m\angle 4$ .

$m\angle 5 = 90^{\circ}-m\angle 3$

Hence, the right answer is E.

Answer:

d. All of the above

Explanation:

A scale can be defined as an ordered numerical or alphabetical sequence that is typically used for taking measurements such as size, weight, height, length, etc. Also, a scale is used in the field of science to assign magnitude to physical activities and natural phenomenons such as an earthquake using the Richter scale.

In Science, there are four (4) main scales of measurement and these includes;

1. Interval scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.

2. Ratio scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.

3. Ordinal scale: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.

4. Nominal scale: it is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.

Hence, scales can represent;

a. A range of information.

b. A range of resources.

c. Proportional measurement.

Beer has a pH of 3, therefore its H⁺ concentration is ____________ times greater than a solution with a pH of 5.

elixir [45]

H+ conc = antilog to negative pH
H+ conc of pH 3 = 1 x 10^-3 M

One unit pH change of the H+ concentration is by a factor of 10. Since pH 3 to pH 5 is 2 unit changes, pH 3 then has one hundred times more H+ concentration than a pH of pH 5.
