Question

0,7
In a right angled triangle, the acute angles
are in the ratio 4:5. Find the angles of
the triangle in degree and radian.​

Answer 1

Answer:

40° ,50° , 2π/9 and 5π/18

Step-by-step explanation:

4:5 ratio, sum of angle of triangle is 180 and one angle is 90

so

4x+ 5x= 90

x=10

4x= 40 ° and 5x=50°

for radian multiply them by π/ 180.

40°=2π/9 & 50°= 5π/18 in radian.
