Answer:
x = 30
Step-by-step explanation:
If the angles are supplementary, that means that they add up to 180°.
That means 40 + 4x + 20 = 180°
Simplify: 60 + 4x = 180
Subtract: 4x = 120
Divide: x = 30

Please correct me if I’m wrong
I believe the answer is 5/4
Sorry if I’m wrong ;(
Answer:
x=30
Step-by-step explanation:
Since this a regular hexagon, each angle measure is congruent.
A hexagon interior angles add to be
(
However, in the triangle, only part of angle b and angle f is in the triangle. However angle a is fully in the triangle so
Angle A=120.
So using the triangle interior theorem, angle b and f must add up to 180.

However, since this is a regular hexagon, the sides are equal so this is a isoceles triangle.
Using the base isoceles triangle theorem, angle b and angle f of the triangle must be equal so




The place the value of 9 is in is the hundreds place. So, any number greater than 5 is rounded up. 7 is greater than 5, so the 9 becomes a 0 and the next number is increased by 1. All the values after are marked as a 0. The answer is 223,000.
