2. 50, 40 degrees

Answer 2

• 63°
• 50° , 40°

Explanation:

1.

`3 :7 \\Acute \: angle = 90\°\\7+3 = 10\\(7)/(10) * 90\\\\= (630)/(10)\\ = 63 \°\\`

2.

`Let \:the\: other\:acute \:angle\: be \:x\\According\:to \:the \:question ; \\ \:\\(2x-30)+x =90\\2x - 30 +x =90\\2x +x = 90+30\\3x = 120\\(3x)/(3) =(120)/(3) \\x = 40 \\\\(2x -30)\\2(40) -30\\80 - 30 = 50\\\\\\Angle \:1 = 50\°\\Angle \: 2 = 40\°\\`
