WebThis means the true value could be anywhere from 20.3 to 29.2, which would be one reason why we might want to round to 30 if we could only have 1 significant digit as it is the … WebSolution: Given: PQ ⊥ PS, PQ SR, ∠SQR = 28° and ∠QRT = 65°. To find: x and y. We know when two parallel lines are cut by a transversal, alternate interior angles formed are equal. According to the angle sum property of a triangle, sum of the interior angles of a triangle is 360°. Since, PQ SR and QR is the transversal,

Web∴ x = 130° We also know that vertically opposite angles are equal. So, y = 130° In two parallel lines, the alternate interior angles are equal. In this, x = y = 130° This proves that alternate interior angles are equal and so, AB CD. (Page No: 104) NCERT Solutions For Class 9 Maths Chapter 6- Lines and Angles 2. WebIf an angle is 30° more than one half of its complement, find the measure of the angle. VIEW SOLUTION. Exercise 10.1 Q 5 Page 7 ... In the below fig, l, m and n are parallel lines intersected by transversal p at X, Y and Z respectively. Find ∠1, ∠2 and ∠3. ... ∠BHS = 110° and ∠ABC = x°. Then the value of x is. 15° ...
Webx = 130°. We know that, if a transversal intersects two lines such that a pair of alternate interior angles are equal, then the two lines are parallel. Here we can see that the pair of alternate angles formed when lines AB and CD are intersected by transversal P are equal. i.e, x = y = 130°. So we can say the two lines AB and CD are parallel. http://www.columbia.edu/~ks20/stochastic-I/stochastic-I-MCI.pdf
Web30. In Fig. 5.25, lines PQ and ST intersect at O. If ∠POR = 90° and x : y = 3 : 2, then z is equal to (a) 126 o (b) 144 o (c) 136 o (d) 154 o. Solution:-(b) 144 o. The sum of all angles about … WebJul 8, 2024 · One angle is equal to three times its supplement. The measure of the angle is. 2. Two complementary angles are such that two times the measure of one is equal to three times the measure of the other. The measure of the smaller angle is. 3. Two straight line AB and CD intersect one another at the point O.
WebNCERT Solutions for class 9 Maths Chapter 6: Lines and Angles is very essencial for getting good marks in CBSE Board examinations Question 1. In Fig. 6.28, find the values of x and y and then show that AB CD. Solution: 50° + x = 180° (sum of angle in linear pair is 180° ) x = 180° -50° x= 130°
