Per current school question and answer enquired students to say what they think is the most crucial important concern for a student to do in order to gain success. The one which response stood out from the rest was practice. People who are definitely successful do not become successful by being born. They work hard and dedicate their lives to succeeding. If you tend to reach your goals, keep this in mind! following some question and answer examples that you could utilise to boost your knowledge and gain insight that will help you to maintain your school studies.
What is the measure of ∠ADC in quadrilateral ABCD?
It is only possible when the value of x is 115 degrees since side AB and CD are congruent. Thus, the value of ∠ADC is 115 degrees.
ABCD is the quadrilateral given in the question in which AD is parallel to BC, and AB is equal to CD. The value of angle BAC is given 115 degrees.
We need to determine the value of the ∠ADC.
Let us assume the value of ∠ADC is x.
The exterior angle of C and the ∠CDA are alternate interior angles. Thus, the value of the exterior angle of C is also x.
We know that sum of interior and exterior angles is always 180 degrees.
Thus, the value of ∠DCB is (180-x).
The exterior angle of B and the ∠BAD are alternate interior angles. Thus, the value of the exterior angle of B is also 115 degrees.
Thus, the value of ∠ABC is (180-115) which is equal to 65 degrees.
Now, the sum of all the angles of the quadrilateral is always equal to 360 degrees.

They could certainly hopefully help the student take care of the question by using the questions and answer examples. Then can make some sharing in a group discussion and also study with the classmate around the topic, so another student also ought to have some enlightenment and still keeps up the school learning.
