Answer:
18°
Step-by-step explanation:
Note that 25% = [tex]\frac{1}{4\\}[/tex]
let x be one angle then the other is [tex]\frac{1}{4\\}[/tex] x
Complementary angles sum to 90°, thus
x + [tex]\frac{1}{4\\}[/tex] x = 90
Multiply all terms by 4
4x + x = 360
5x = 360 ( divide both sides by 5 )
x = 72
The smaller angle = [tex]\frac{1}{4\\}[/tex] × 72° = 18°
