Question

Find the length of the unknown sides in the following figures.​

Answer 1

Answer:

You need to find Hypotenuse, as you have right angle triangle

Step-by-step explanation:

1. Take 15 cm as a^2, and 8 cm as b^2

2. therfore take side 'x' as c^2

3. as per the Pythagoras Theorem, a^2 + b^2 = c^2

4. so (15)^2 + (8)^2 = (Hypotenuse)^2

5. So 225 + 64 = 289

6. Find square root of 289.

7. Answer = 17 cm

Answer 2

Answer:

b) (15)square + (8)square

=225+64

=(289)

=17

c) (24)square +(7)square

=576+49

= (625)

= 25

d) (15)square - (12)square

=81

= 9
