Answer:

-66

Step-by-step explanation:

- 13, ____, -119

first, find the common difference:

-13 - (-119) = 106

next, divide 106 by 2: $\frac{106}{2}$ = 53

so, the common difference is 53.

now, subtract 53 from -13:

-13 - 53 = -66

I think you have to use the pythagorean theorem, would like you to explain how you did it as well, thanks!

Olegator [25]

Answer:

Step-by-step explanation:

Pythagoras theorem states that:

In a right-angled triangle,the hypotenuse , altitude and base are related as:

$(Hypotenuse)^2=(Base)^2+(Altitude)^2$

In this question:

Hypotenuse = 20 units

Base = 12 units

Altitude = w = ?

By Pythagoras theorem:

$20^{2}=12^{2}+w^2\\w=\sqrt{400-144}=\sqrt{256}\\w=16\ units$

Hence w = 16 units.
