Question

Please answer is correctly with reason​

Answer 1

Answer: I) 45,45     II) 100, 80         III) 54, 36

( all in degrees)

Step-by-step explanation: ( all in degrees)

I) let one angle be x then other is also x

SO, 2x=90

x =45

II) let one angle be x

Then, other = 4/5x

Now, x+4x/5 = 180

9x/5 =180

x=100, and other angle = 80

III) let one angle be x

Then, x+2x/3 = 90

5x/3 =90

x= 54, other angle =36
