Answer:
<em>x = 49°</em>
Step-by-step explanation:
<u>Angles in a Triangle</u>
The sum of the internal angles in any triangle adds up to 180°.
The figure shows a triangle that includes two angles with the same tick mark. This means they are congruent, i.e. they measure the same.
The larger triangle has three defined angles: 43°, 39°, and 2x. Since the sum of them is 180°:
43° + 39° + 2x = 180°
Operating:
82° + 2x = 180°
Subtracting 82°:
2x = 180° - 82° = 98°
x = 98°/2 = 49°
x = 49°
Answer:
Step-by-step explanation:
y = - 3
the equation of a horizontal line, parallel to the x- axis is y = c where c is the value of the y- coordinate the line passes through
Line passes through ( - 7, - 3) → y- coordinate is - 3
equation of line is y = - 3
Answer:
Step-by-step explanation:
If the given polygon is a regular polygon, its sides are equal.
This means:
Subtract 
to both sides
4 = x
OR
x = 4
