The answer is 58, acute as the angle doesn't go farther than a straight line which means it is acute and u can eliminate the other acute answer!! pls mark brainliest if i helped:)

Use slope to determine if lines PQ and RS are parallel, perpendicular, or neither P(-3,14) q(2,-1) r(4,8) s(-2,-10)
Vlad1618 [11]

Answer:

Neither

Step-by-step explanation:

The slope of PQ is -3.

The slope of RS is 3.

Parallel lines have the same slope. The slopes for perpendicular lines are the opposite of the reciprocal. PQ and RS are intersecting lines, but not parallel or perpendicular.

Leya [2.2K]

The dependent variable depends on a particular situation. The independent variable does depends on the result of an experiment. The controlled variable is a variable whose value is constant.

What is dependent variable?

The variable being measured or tested in an experiment is known as the dependent variable. The results of the participants' tests, for instance, since that is what is being measured, would be the dependent variable in a study looking at how tutoring affects test scores.

What is independent variable?

This isn't the same as an experiment's independent variable, which is a variable that can stand on its own. Tutoring would be the independent variable in the aforementioned case. The dependent variable (test results), however, may alter depending on the independent variable (tutoring).

What is controlled variable?

Anything kept constant or constrained in a research study is referred to as a control variable. Despite not being relevant to the study's objectives, this variable is controlled because it might have an impact on the results.

Numbers called parameters are used to define the characteristics of entire populations. Statistics are numerical representations of sample characteristics. One population parameter is the average income in the United States.

Find x(3x+72) triangle
Alinara [238K]

Answer: x = -4 ; Angle = 60°

Concept:

The given figure is a triangle with 3 arc signs on each angle. This <u>arc sign </u>stands for the corresponding angles are congruent, which in this question, it shows that all three angles are congruent. Sometimes, if the figure has multiple angles and there are different groupings of congruent angles, then we use different numbers of arcs or symbols.

Solve:

<u>Given information</u>

An angle = 3x + 72

Total measure of angles = 180 (triangle angle sum theorem)

Total number of congruent angles = 3

<u>Given expression</u>

Total measure = Total number of congruent angles × An angle measure

<u>Substitute values into the expression</u>

180 = 3 (3x + 72)

<u>Divide 3 on both sides</u>

180 / 3 = 3 (3x + 72) / 3

60 = 3x + 72

<u>Subtract 72 on both sides</u>

60 - 72 = 3x + 72 - 72

-12 = 3x

<u>Divide 3 on both sides</u>

-12 / 3 = 3x / 3

\boxed{x=-4}

<u />

<u>Find the angle measure</u>

3x + 72 = 3 (-4) + 72 = \boxed{60}

Hope this helps!! :)
