Question

In a right triangle, the two smaller angles are in the ratio 5:4. Compute these angles.
a) 60 degree, 30 degree b) 50 degree, 40 degree c) 20 degree, 70 degree d) None of these​

Answer 1

Answer:

50 degree and 40 degree

Step-by-step explanation:

5:4 can be written as 5x:4x if we multiple both 5 and 4 by 10 then we get 50 and 40 .

It is not necessary for multiplying both the digit by 10 it can be 5 or any number but Both should be multiplied by same

Answer 2

Step-by-step explanation:

the sum of all the angle of a triangle is 180

so 90 + a + b= 180( im taking 5=a and 4=b )

so 5:4 ratio is = 180 - 90

=> a + b = 90

5 + 4 = 9

90/9 = 10

now,5*10 = 50

       4*10 = 40

=50 + 40 + 90 = 180

so the right option is B

therefore solved.

hope this will help u
