Answer:
1. Draw a line segment BC = 6 cm.
2. With B as a center and radius 2.5 cm, draw an arc.
3. With C as a center and radius 6.5 cm, draw another arc, cutting the previous arc at A.
4. Join AB and AC.
Then, ΔABC is the required triangle.
5. When we will measure the angle B of triangle by protractor, then angle is equal to ∠B = 90o
Answer:
I) Factors Of 60 in Pairs
Let us see the factor pairs of 60. Therefore, the factors pairs of 60 are (1, 60), (2, 30), (3, 20), (4, 15), (5, 12) and (6, 10).
ii) Distinct Factors of 5427 = 1, 3, 9, 27, 67, 81, 201, 603, 1809, 5427, Note: Factors of 5427 and Distinct factors are the same.
iii) First five multiples of 11: 11,22,33,44,55
First 5 multiples of 13: 13,26,39,52,65
Iv) Yes, \(29\) is the factor of \(743067\).
v) Three pairs of Prime Numbers whose difference is 2 are (5, 7), (11, 13) and (17, 19) A pair of prime numbers whose difference is 2, is called Twin Prime.
