The measure of one angle of an octagon is two times smaller that of the other seven angles. What is the measure of each angle?

Anestetic [448]

Answer:

7 of the angles measure 144 degrees each and one angle measures 72 degrees

Step-by-step explanation:

Let

x -----> represent the measures of the seven same-size angles,

x/2 ----> represent the measure of the one that is "two times smaller."

we know that

The sum of internal angles of a polygon can be calculated as:

$S=180^o(n-2)$

where

n is the number of sides of the polygon

In this case

n=8 (octagon)

substitute

$S=180^o(8-2)=1,080^o$

The linear equation that represent this problem is

$\frac{x}{2}+7x=1,080$

solve for x

$\frac{15x}{2}=1,080\\\\15x=2,160\\\\x=144^o$

$\frac{x}{2}=72^o$

therefore

7 of the angles measure 144 degrees each and one angle measures 72 degrees

Plz help me.. 50 points if you answer all ill give brainliest

antoniya [11.8K]

1) 1/4+1/2

We need to convert the fractions.

1/4 is fine.

1 x 2=2

2 x 2=4

1/4+2/4=3/4

2) a+a

a can be written as 1a.

1a+1a=2a

I can't see photos and he doesn't know 3 or 4 and i'm confused on 5.

a=?

Hope it helps?
