Question

21. m the given figure. ray QS perpendicular to line PR. If a:b= 7:ll find
and reflex angle TQR.​

Answer 1

Answer:

235°

Step-by-step explanation:

let a = 7x & b =11x

7x + 11x = 90° => x = 5

a = 7x = 7× 5 = 35°

angle TQR = a + 90° = 35+90 = 125°

reflex angle of TQR

= 360° - 125° = 235°

Answer 2

Answer:

a + b = 90

if a = 7x then b = 11 x

or 7x + 11x =90

or x =5

this means a = 7×5 =35

You need is360° -( 90 ° + 35 °) = 225°
