Question

If one acute angle of a right-angled triangle measures 18" less than the other acute angle, then the smaller acute angle of the triangle is​

Answer 1

Answer:

36

Step-by-step explanation:

if 1 angle is 90 deg.

then the sum of the remaining 2 angles will be 90 by angle sum property

Let the larger angle be x

and smaller angle x-18

therefore (x) + (x-18) = 90

2x = 108

x = 54

therefore the smaller angle = 54 - 18

= 36
