Hey there! :)

Answer:

98°

Explanation:

The polygon shown contains 7 sides. Therefore:

Use the sum of interior angles formula to derive the sum of all of the angles:

(n-2)180 = sum

(7-2)180 =

5(180) = 900°

Subtract all of the angles shown from the total sum to derive the value of x:

900 - 146 - 122 - 142 - 140- 110 - 142 = 98°

m∠x = 98°.

Answer:

x = 98°

Explanation:

We know that in a heptagon, there are 900°. So,

900 - (146 + 122 + 142 + 140 + 110 + 142)

We plug that into the calc and we should get 98 as our final answer!
