Answer:
The measure of ∠A is 127°.
Step-by-step explanation:
The interior angles of a triangle always add up to 180°. Since you can fix <em>three</em> triangles into a pentagon, the sum of its interior of angles is 540° You could also look at how many angles there are (5), multiply that number by 180°, then subtract 360° from the product.
540° - (113° + 80° + 130° + 90°) = ∠A
540° - 413° = 127°
∠A = 127°

1) 1 dot
2) figure 1 + 3 dots
3) figure 2 + 5 dots
4) figure 3 + 7 dots
5) figure 4 + 9 dots
and keeps going....
The next figure, takes the solution of last figure and add odd number in increasing order.
In this type of problem, find a matter.
If dimensions are multiplied by 3 then area is multiplied by 3^2
I got 4.5 for question 2 and 597 1/4 for question 6. Idk if im right
