Question

In a Right Angled Triangle ABC where angle A= 90° and AB=AC. What is measure of angle B ? OR If two adjacent angles on a straight line are in the ratio 1 : 3, find the measure of Smaller angle. ​

Answer 1

Answer:

45 degree ...........

Answer 2

Answer:

a) the measure of angle B is 45 degrees

b) The measure of the smaller angle is 45 degrees

Step-by-step explanation:

a) a= 90

   sum of the angles in a triangle= 180

   180 - 90 = 90

   90/2 = 45

b) 1 : 3 = 180

   1 + 3 = 4

   180 / 4 = 45

   36 * 1 = 45
