Question

in a right angle one of the acute angle is 4 times the other then the measure of the greatest acute angle is

Answer 1

Sum of the three angles of a triangle = 180

Sum of two angles =(90 + 52 ) = 142 [since it is right angled triangle one angle is 90 ]

Third angle is 180 - 142 =38

Another way of calculating the third angle is 90–52 =38[as already one angle is 90]

Answer 2

Answer:

Step-by-step explanation:

smaller angle = x

Thus bigger angle is 4x

4x+x+90=180. Angle sum property

Thus, 5x =90

x=18

4x=72
