Question

In a right angle - triangle the two acute angles
are in the ratio 4:5 find the angles ​

Answer 1

Answer:

let angles be 4x, 5x

since another angle is 90°

i.e.,

4x+5x+90 = 180

9x = 90

x= 10

so angles are 4*10,5*10

= 40°,50°

Step-by-step explanation:

Answer 2

$4x + 5x + {90}^{0} = 180 {}^{0} \\ 9x + 90 {}^{0} = 180 {}^{0} \\ 9x = 180 {}^{0} - 90 {}^{0} \\ 9x = {90}^{0} \\ x = \frac{90 {}^{0} }{9} \\ = 10 {}^{0} \\ agles \: are \: 40 {}^{0} and \: {50}^{0}$
