Answer: B. YesStep-by-step explanation:We have been given that in parallelogram ABCD, D is a right angle. We are asked to determine whether the given parallelogram is rectangle or not.Let us recall parallelogram properties.Opposite angles of parallelogram are equal.Consecutive angles of parallelogram are supplementary.Since D is a right angle, so its opposite angle will be right angle as well and consecutive angles of angle D will be right angles as well.Therefore, the parallelogram ABCD is a rectangle and option B is the correct choice.
Step-by-step explanation:
Hey there!
4x - 16 + 2x + 16 = 180 (linear pair)
4x + 2x - 16 + 16 = 180
6x = 180
x = 180/6
<u>x </u><u>=</u><u> </u><u>3</u><u>0</u><u>.</u>
Hope it helps ya!
Answer:
The correct answer is:
The score on the achievement test (A)
Step-by-step explanation:
Please note that the terms "response variable" can be used instead of "dependent variable", and the dependent variable is a variable whose outcome is as a result of the change in the independent variable. It is the variable that the experimenter sets out to study in an experiment.
In this example, the score of the achievement test is a measure that tells of how effective the teaching method was on the selected group, and this is the dependent variable because it completely depends on the teaching method employed.
Please note that the dependent variable is another kind of variable and it is one that is completely under the control of the experimenter. In this case, the teaching method is the dependent variable.
Answer:
rad66/11
Step-by-step explanation:
Using Sohcahtoa, you can find that the tangent is the opposite side over the adjacent side. This means that the tangent of angle X is 2rad6/2rad11. You then simplify it to rad6/rad11. Preferably, a radical shouldn't be in the denominator. You can muliply both sides by rad 11 to balance the equation into rad66/11.
First you add 3 twice to both sides of the swimming pool
12 + 6 = 18
15 + 6 = 21
The perimeter is the sum of all sides therefore
18 + 18 + 21 + 21 = 78
The answer is A
