One angle of a triangle measures 136°. The other two angles are congruent. Enter and solve an equation to find the measure x of
Juliette [100K]

<u>136 + x + x = 180. Or, to simplify, 136 + 2x = 180. The congruent angles measure 23 degrees each.</u>

We know this because of a simple rule that goes for all triangles: The measures of all three angles in a triangle will <em>always</em> add up to 180 degrees.

One angle of a triangle measures 136 degrees. The other two angles are congruent (have the same measure).

(x stands for an unknown angle measure.) So the equation we would use is 136 + 2x = 180. We can solve this within a few steps.

1. We subtract 136 from 2x in order to isolate 2x. But if we subtract something from the left side of the equation, we have to subtract it from the right side too. Otherwise the equation will be wrong; We would be taking away the balance.

2x = 180 - 136

2. Now that 2x is isolated, we solve 180 - 136.

2x = 46

3. If we know now that 2x is equal to 46, how do we find out what x is equal to? We divide by 2 (on both sides or it'll be wrong) to get x.

2x = 46

2x/2 = 46/2

x = 23

Now we know! x = 23... The other two angles are both 23 degrees. We can check to see if that's right by solving 23 + 23 + 136... Does it add up to 180? Yes! :)

Marla will paint 48 pots . She plans to paint 9 pots each week . Draw an array to find how many weeks it will take Marla to pain
Leni [432]

Answer:

The number of weeks Marla will take to paint all the pots is  5 weeks and 3 days .

Step-by-step explanation:

Given as :

The number of pots Marla will paint = 48 pots

The number of pots she plans to paint each week = 9 pots

Let The number of weeks Marla needs to paints all pots = n weeks

<u />

<u>Now, According to question</u>

The number of weeks = \dfrac{number of pots Marla will paints}{\textrm The number of pots Marla will paints each week}

Or , n = \dfrac{48}{9}

∴ n = 5.3

So The number of weeks =  n = 5 weeks and 3 days

Hence The number of weeks Marla will take to paint all the pots is  5 weeks and 3 days . Answer

The smallest angle would be 19 degrees. So option D is correct.

<h3>What is the sum of the octagon?</h3>

The sum of exterior angles of the regular octagon is 360 degrees.

Given;

The angles

x + 13 + 2x - 1 + 2x + 6 + 2x + 12 + 2x - 17 + 3x - 4 + 3x - 10 + 4x = 360

19x - 1 = 360

19x = 359

x = 18.89

The smallest angle would be

2x - 17 = 2(18.89) - 17 = 19
