Given the triangle is a right-angled triangle. Therefore one angle is 90 degrees. Also, the sum of the angles of a right-angled triangle is 180 degrees.
x+58+90=180
x+58=90
x=90-58
x=32 degrees
The acute angles of a right angled triangle is 58 degree ,
Sum of right angled triangle is 90 degree
Then ,
Let the other be x
X + 58 degree = 90 degree
X = 90 degree - 58 degree
X = 32 degree
Hence , the other number is 32 degree answer ....
