5)In a right angle triangle, if sum of the squares of the sides making right angle is 169 then what is the length of the hypotenuse .
...................​

Answer 1

Answer:(1) The value of 2tan45°-2sin30° is 1

(2) 36 [reason: By theorem of geometric mean]

(3) 36cm

(5) 13 [reason:taking square root]

Answer 2

1)The value of 2 tan 45 degrees minus 2 sin 30 degrees is 1

2)Altitude on the hypotenuse of a right-angle triangle divides it into two parts of lengths 4 cm and 9 cm. Find the length of the altitude?

13 cm

3)find the perimeter of a sector of a circle if its measure is 90 degrees and the radius is 7 cm.

10.99

4)A-line makes an angle of 30° with the positive direction of the x-axis. So the slope of the line is 1/root3

5)In a right angle triangle, if some of the squares of the sides making the right angle is 169 then what is the length of the hypotenuse.
