The missing interior angle, x, of the convex polygon is 168⁰.
<h3>
Sum of interior angles of convex polygon</h3>
The sum of interior angles of a convex polygon is calculated as follows;
S = (n - 2) 180
S = (8 - 2) 180
S = (6) 180
S = 1080
The missing interior angle, x, is calculated as follows;
x + 126 + 146 + 130 + 140 + 146 + 134 + 90 = 1080
x + 912 = 1080
x = 1080 - 912
x = 168⁰

According to the vertical angle theorem when two lines intersects each other, the vertical angles that are formed are congruent to each other.
So, angle XWY is 74 degrees.

Answer:
B: x=-1
Step-by-step explanation:
5x+6=1
5x+6-6=1-6
simplify
divide by 5 on both sides
x=-1
To simplify the fraction, divide the numerator / denominator ( cancel ) by the highest common factor of 25 and 30, that is 5
= in simplest form
