Question

In the figure,
what is the value of m?
(1) 15 (2) 14.5
(3) 24 (4) 24.5
(2m - 5)​​

Answer 1

Answer:

14.5

Step-by-step explanation:

as we are given that ABC is a right angled triangle so by Pythagoras theorem:-

25^2 - 7^2= (2m-5)^2

625-49= (2m-5)^2

576=(2m-5)^2

24^2=(2m-5)^2

24=2m-5

29=2m

m=14.5
