Question

I need fully solved fast pleaseee​

Answer 1

He exercises for 18 minutes daily

Step-by-step explanation:

Angle G and Angle H are co interior angles hence they are supplementary

Angles LGH and LGB would be equal because bisector divides angle into 2 equal halves.

In the same way Angles LHD and GLH are also equal.

So let Angles LGH and LGB be' a' and 'a'

And angles LHD and GLH be 'b' and 'b 'respectively

So, a+a+b+b = 180

2a+2b = 180

2(a+b) = 180

a+b =180 ÷ 2

a + b = 90

If we observe a,b and x are in a triangle so by angle sum property they are all equal to 180

a+b+x = 180

90+x = 180

x = 180 - 90

x = 90

Minutes of exercise = x ÷ 5

= 90 ÷ 5

= 18 minutes
