In both the figures we have a Right Angled Triangle.

Two sides of the right angled triangles are given and we are to find the Third side. This can be done using the Pythagoras Theorem, which states:

Hypotenuse² = Base² + Perpendicular²

For 1st figure, we have
Base = 21
Perpendicular = 20

So, 

Hypotenuse² = 20² + 21² = 841
⇒
Hypotenuse = 29 (1st option is correct)

For 2nd Image, we have
Base= 6
Hypotenuse = 10

So, we can write:

10² = 6² + Perpendicular²
Perpendicular² = 64
⇒
Perpendicular = 8 (Option Fourth)

Help me plz. I dont understand.
Ahat [919]
For this, you would use simultaneous equations.

w=walnuts
a=almonds

3w+6a=51
5w+4a=55

Find a way to make one of the unknowns equal. since we are trying to work out the price of a pound of walnuts, I am going to make a equal on each side to leave us with w. This leaves us with:

15w+12a=165
6w+12a=102

Then take them away to leave w:

9w=163

Then solve:

w=163/9
= 18.11111111...

Then round it to 2 decimal places as the measurement is currency.

So 1 pound of walnuts equals $18.11
