1.	4. Ifone acute angle of a right angled triangle is 45", then lind anotherangle.50 each, then find the third angle,
Answer» right angle triangle means 90•hence the sum of angle of triangle is 180• 45•+90•+x=180•135•+x=180•x=180•-135•x=45• 45• is right answer Given:One acute angle is 45°The angle-sum property will be, 180° = 90° + 45° + x180° =135 ° + xx = 180° - 135°x =45 ° Therefore the other acute angle is 45°

4. Ifone acute angle of a right angled triangle is 45", then lind anotherangle.50 each, then find the third angle,

Answer»

right angle triangle means 90•hence the sum of angle of triangle is 180•

45•+90•+x=180•135•+x=180•x=180•-135•x=45• 45• is right answer

Given:One acute angle is 45°The angle-sum property will be,

180° = 90° + 45° + x180° =135 ° + xx = 180° - 135°x =45 °

Therefore the other acute angle is 45°
