Aight let's answer this step by step

What you need to know is if two values are equal either one will be similar to the other it's only the format that's different if you calculate each of the fractions you'll see each pair is equal except for the last option

Where if calculated

8/3=2.67 but

5/4.8=1.04

Therefore values aren't equal to each other

the measure of the seven angles in a nonagon measure 138, 154, 145, 132, 128, 147 and 130. if the two remaining angles are equal

Juliette [100K]

To find the missing two angle measures, you will need to know that the sum of all nine angles in a nonagon equal 1260 degrees.

Knowing this, you can use this total to find the missing congruent angles.

Start with the total and subtract what you know. Divide what is left by two to get each angle measure.

1. 1260 - ( 138 + 154 + 145 + 132 + 128 + 147 + 130) = 286

2. 286/2 = 143

The missing angles are each 143 degrees.

If 3x is one factor of 3x²-9x what is the other factor 1. 3x 2. x²-6x 3. x-3 4. x-3

DaniilM [7]

3x²-9x is a binomial, so if you divide it by 3x, the quotient will also be a binomial:

3x²-9x
--------- = x - 3 (answer)

Look at the triangular prism below. Each triangular face or the

Goryan [66]

Answer:

The volume of the triangular prism is $V=72\ cm^3$

Step-by-step explanation:

we know that

The volume of the triangular prism is equal to

$V=BL$

where

B is the area of the triangular face

L is the length of the prism

step 1

Find the area of the triangular face

The area of a triangle is equal to

$B=\frac{1}{2} bh$

we have

$b=3\ cm\\h=4\ cm$

substitute

$B=\frac{1}{2}(3)(4)=6\ cm^2$

step 2

Find the volume

we have

$B=6\ cm^2$

$L=12\ cm$

substitute in the formula of volume

$V=6(12)$

$V=72\ cm^3$
