we all know that. the sum of three angles of a triangle is 180degree.
given = two acute angles are equal
let the equal angles be angle a and b and the 90degree angle be c.
so,
a + b + c =180degree
a + b + 90degree = 180degree
a + b = 180degree - 90 degree
a + a = 90 degree. ( b = a )
2a = 90degree
a = 90 degree / 2
a= 45 degree
since , a and b are equal they both are of 45 degrees.
a = b = 45degrees.
so , the three angles are 90degree , 45degree , and 45 degree respectively.
please put the sign of degree where degree is written.
hope it helps

the sum of the total angle of a triangle is 180
right angle is 90
therefore, 90+x+x =180
90+2x=180
2x=180-90
2x =90
x=90/2
=45
therefore the measures of three angle is right angle , x, 1+x
=90,45,46.
