Yes they are congruent because they have just been translated in a rotation. But they still hold the same area and perimeter.
Answer:
Independent variable- time spent in the dark room
Dependent variable - number of objects correctly identified
Conditions of the experiment- low light environment and lighted environments
Scores from the independent variable are used to construct the frequency distribution
Step-by-step explanation:
The independent variable is the factor that is being manipulated in an experiment and this time it is the time spent in a darkened room.
The dependent variable is the response variable, in this case, the number of objects correctly identified.
The experimental conditions involved bringing people from a lighted area into a darkened room.
-say in the situation "C" was "X"; angle ∠C and ∠D are supplementary angles so ∠D-180=∠C
-all triangle, angles sums =180° so ∠A+∠B+∠C=180
-if the triangle were to be a right triangle you could use 30,60,90 or 45,45,90 but you need to know the measure of one of 2 of the angles
Answer
First subtract: 13 1/2 - 7 1/3 = 37/6
Second simplify: 37/6 = 6 1/6
HI THERE LET ME HELP U WITH YOUR QUESTION
**PERFECT SQUARES ARE POSITIVE INTEGERS**<span>
</span>THE NUMBERS CANNOT INCLUDE ITSELF AND ALWAYS SHOULD HAVE A ONE IN IT.
2.89 AND 0.004 ARE PERFECT NUMBERS. THEY INCLUDE 1 AND THEY DONT INCLUDE ITSELF
