Answer 1

Step-by-step explanation:

Hi friend!!

Since ABC is a right angled triangle, 25,7 and one more number should form a Pythagorean triplet.

The number is 24.

The given expression is 2m - 5

2m - 5 = 24

2m = 24 + 5 = 29

m = 29/2 = 14.5

The answer is (2) 14.5

Hope it helps!!!

Answer 2

Answer:

(2) 14.5

Step-by-step explanation:

Since ΔABC is right-angled triangle.

Therefore we can use Pythagoras Theorem to get the answer.

∠B=90° Therefore AC is the hypotenuse.

Pythagoras theorem states that the square of hypotenuse is equal to sum of the square of other two sides

That is

(Hypotenuse)²=(Base)²+(Perpendicular)²

(25)²=(7)²+(BC)²

625 - 49=(BC)²

(BC)²=256

BC=24

2m - 5=24

2m=24+5

m=29/2

m=14.5

Therefore the correct option is (2) 14.5
