Answer:
684 ft^2
Step-by-step explanation:
You can find the area of the middle rectangle by using:



You can find the area of a triangle by using:

Triangle 1: A=90
Triangle 2: A=72
2(72+90)+360
324+360
684
Answer:
m∠EGF = 65° and m∠CGF = 115°
Step-by-step explanation:
Given;
∠EFG = 50°
EF = FG
Solution,
In ΔEFG m∠EFG = 50° and EF = FG.
Since triangle is an isosceles triangle hence their base angles are always equal.
∴
Let the measure of ∠EGF be x.
∴ 
Now by angle Sum property which states "The sum of all the angles of a triangle is 180°."
m∠EFG + m∠FEG + ∠EGF = 180

Hence
m∠EGF = 65°
Also 'The sum of angles that are formed on a straight line is equal to 180°."
m∠EGF + m∠CGF = 180°
65° + m∠CGF = 180°
m∠CGF = 180° - 65° = 115°
Hence m∠EGF = 65° m∠CGF = 115°
Answer:The third angle would be 60⁰
Step-by-step explanation: Since a triangle adds up to 180⁰, 40 + 80 = 120⁰. And 180 - 120 = 60⁰.
Step-by-step explanation:
Radius = 4 ft
Side of the square = 8 ft
Area of circle = πr² ≈ 3 × 4² = 48 ft²
Square area = a² = 8² = 64 ft²
area of composite shape = Square area - Area if circle = 64 - 48 = 16 ft²
Add like terms. Ignore parenthesis. And change the negative in front of the 2 into a positive. 4y minus y and 3 plus 2 makes... 3y+5
