Question

in a right angle triangle the two acute angle are in ratio 4 ratio 5 find the measure of the angle of the triangle​

Answer 1

Answer:

40° and 50°

Step-by-step explanation:

sum of angles of a triangle=180°

one angle=90°

∴sum of other two angles=180°-90°

                                             =90°

ratio of the remaining angles=4:5

∴4x+5x=90°

 9x=90°

 x=90°/9=10°

 ∴ the angles=40° and 50°

Answer 2

Step-by-step explanation:

mark angles a b c

a is 90degree as it is right angled triangle

sum of all angles of triangle is 180degree

90+4x+5x = 180

9x = 180-90

9x = 90

x = 90÷9

x = 10

therefore the angles are 4x = 10×4 =40

5x = 10×5 = 50
