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:
16/5
Step-by-step explanation:
Since y varies inversely as x, then xy = k
2(8) = 16 = k
Therefore, xy = 16
Now, 5x = 16
x = 16/5
Answer:
A. 16.86 square inches
Step-by-step explanation:
Area of Circle = 
, where r = radius.
Area of Rectangle = 
, where l = length and w = width.
We are given the radius of the circle as 1, and we use π as 3.14
Next, we find the area of the rectangle.
Lastly, we subtract 3.14 from 20.
Therefore, the answer is A. 16.86 square inches.
Answer:
the most is 8.8 miles
Step-by-step explanation:
3 + 1.25m <=14
1.25m <=14 -3
14-3=11
1.25m<=11
m<=11÷1.25
m<=8.8
The height(zipper) would be 3 feet or 36 inches
