<h3>
Answer:</h3>
90°
<h3>
Step-by-step explanation:</h3>
The polygon has 7 sides, so the total of internal angles will be ...
... 180°×(7 -2) = 900°
The sum is then ...
... x + 146° +122° +142° +140° +110° +142° = 900°
... x + 802° = 900° . . . . . simplify
... x = 98° . . . . . . . . . . . . .subtract 802°

<em>Comment on angle measure formula</em>
The usual formula for computing the total of internal angles of a convex polygon with n sides is ...
... total angle measure = (n -2)×180°
This can be simplified from the fact that the sum of external angles is always 360°. That is, for internal angles a1, a2, ..., an, the sum of external angles is ...
... (180° -a1) +(180° -a2) +... +(180° -an) = 360°
... n×180° -(a1 +a2 +... +an) = 360° . . . . . . collect terms
... n×180° -360° = (a1 +a2 +... +an) . . . . . . add ∑ak -360°
... 180°×(n -2) = a1 +a2 +... +an . . . . . . . . . factor out 180°
The sum of 4,506 and 5,933 is 10,439.
The answer is 121 because 2x3 you do first which is 6 then 6+5 is 11 and 11x11 is 121 which is your answer
Answer:
15
Step-by-step explanation:
Each bracelet takes 28+10 = 38 elastic bands. If you have 600 bands, you can make ...
600/38 = 15 30/38 . . . bracelets
You can make 15 complete bracelets.
__
You will have 30 elastic bands left over.
Using distributive property, it would become 14x.
