Answer:
A ≈ 269.81 cm²
Step-by-step explanation:
This shape is a hexagon (it has 6 sides) so let's use the formula for the area of a hexagon.
A = 
Where s is the length of the sides
Substitute:
A = 
A = 
Solve:
A = 
A = 
Multiply the numerator:
A = 
A ≈ 
(The numerator reflects a rounded number, but the actual calculations are exact)
Divide the fraction:
A ≈ 
A ≈ 2.6(100)
Multiply:
A ≈ 2.6(100)
A ≈ 269.81 cm²
Therefore, the area is approximately 269.82 cubic centimeters.

Answer:
100°
Step-by-step explanation:
The sum of the angles in a triangle is 180°
180°-30°-50°=100°
That isn’t right I don’t think, if a was 47 then it would be wayyyy bigger of a number. You are finding how 7a-2 is 47. First add 2 to both sides making it 7a=49
7 times what is 49?
That is a
