Answer:
The fraction of the students who failed to went partying =
Step-by-step explanation:
Let total number of students = 100
No. of students partied are twice the no. of students who not partied.
⇒ No. of students partied = 2 × the no. of students who are not partied
No. of students partied before the exam = 20 % of total students
⇒ No. of students partied before the exam = × 100
⇒ No. of students partied before the exam = 20
No. of students who not partied before the exam =
Thus the fraction of the students who failed to went partying =
Answer:
Part A:
Part B. All angles are same, so the triangles are similar.
Part C. RP = 8
Step-by-step explanation:
We are given a right angled triangle with
.
PS is perpendicular to the hypotenuse RQ of and S lies on RQ.
Part A:
To identify the pair of similar triangles.
.
Part B:
To identify the type of similarity.
Kindly refer to the image attached in the answer area.
Let us consider the triangles .
Also, is common to both the triangles under consideration.
Now, we can see that two angles of two triangles are equal.
So, third angle of the two triangles will also be same.
i.e. All three angles of two triangles are equal to each other.
So, by A-A-A (Angle - Angle - Angle) similarity, we can say that .
Part C:
RS = 4
RQ = 16, Find RP.
There is one property of similar triangles that:
The ratio of corresponding sides of two similar triangles is equal.
i.e.
