Using the exterior angle of a polygon theorem, the value of the missing angle is 58°
<h3>Calculating the value of a missing angle </h3>
From the question, we are to calculate the value of the missing angle.
From the given information, the missing angle is (3x -2)°.
To calculate the value of the missing angle,
First, we will determine the value of x
From the <em>Exterior angle of a polygon theorem</em>, we can write that
90° + (3x + 12)° + (4x - 10)° + (3x - 2)° + 70° = 360°
(3x + 12)° + (4x - 10)° + (3x - 2)° = 360° - 70° - 90°
3x° + 12° + 4x° - 10° + 3x° - 2° = 200°
10x° = 200° + 2° + 10° - 12°
10x° = 200°
x = 200/10
x = 20
The missing angle is (3x -2)°
Substitute the value of x
(3(20) -2)°
= (60 -2)°
= 58°
Thus,
The missing angle measure is 58°

Answer:
3x+4 = 5
3x = 5-4
3x = 1
x = 1/3
Since the value of x is found, next step is to substitute it to the x for 6x+7
Value of 6x+7:
6(1/3)+7
6/3+7
2+7

A. a + ( - a)
Because it’s the same thing as: a - a
And if you plug in any value for example:
2 - 2 that would be 0

<h2>Answer:</h2><h2><u>-1 </u></h2><h2>
6 </h2><h2 /><h3>
Find the least common denominator</h3>
6 is our least common denominator, so multiply <u>2⋅3=6</u>, and do the same thing to the numerator. <u>1⋅3=3</u>
<u>now, the second fraction. 3⋅2=6</u>
Again, if you multiply from the bottom, do it to the top.
<u>2⋅2=4</u>
<h3>3/6-4/6= -1/6</h3>
(3 - 4 = -1)
