    Answer:

    As we know that the sum of all the three angles of a triangle is 180  


     and a right angle is 90  


    .

    Number of right angles in a triangle =  

    90  


     

    180  


     

    ​  

    =2

    Hence proved.


    Say X= smaller acute angle in right triangle  

    4X= larger acute angle  

    90  


    = right angle  


    x+4x+90  


    =180  

    5x=90  


     

    x=18  


     

    4x=72  


     


    Acute angles are 18  


     and 72

    Answer:

    THE ANSWER IS:

    •OPTION B)

    Step-by-step explanation:

    •SUM OF 3 ANGLES OF A TRIANGLE – 180°

    •ONE RIGHT ANGLE – 90°

    SO,2 RIGHT ANGLE – 2 x 90° = 180°

    SO,SUM OF THE 3 ANGLES OF TRIANGLE =

    2 RIGHT ANGLES.

    HOPE IT HELPS YOU.
