x = 132 - 42

x = 90

Answer

A triangle has an area of 30 square centimeters.
Daniel [21]

Answer: 10.9 cm

Step-by-step explanation:

The equation to find the area of a triangle is

Base x height x 1/2 = area

Since you are given the area, rearrange or “do the opposite” to find the base

(Area x 2 ) / height = base

30 x 2 = 60

60/ 5.5 = 10.9

Hope this helped :)

9,3,1, what is the sequence and what is it equal to?
Thepotemich [5.8K]

Answer: the sequence is to divide by 3 and it gets smaller and smaller by dividing by three I don't think there is an end to it.

Step-by-step explanation:

9/3=3

3/3=1

1/3=1/3

1/3/3=1/9

1/9/3=1/27

1/27/3=1/81

and I think you know what I mean by now right?
