Answer:
Step-by-step explanation:
Division property of equality states that you divide the same number to both sides of an equation.
Given the formula:
...[1]
Solve for G:
Apply the division property,
Divide both sides by Mr in equation [1] we have;
Simplify:

Answer:
∠ECD is 110°
Step-by-step explanation:
For a cyclic quadrilateral,
∠ABC + ∠AEC = 180°
Therefore ∠AEC = 180° - 45° = 135°
∠CAE + ∠ACE + ∠AEC = 180° (Angles in a triangle)
Therefore ∠CAE = 180 - 20 - 135 = 25°
∠CAE = ∠CDA = 25° (Base angles of isosceles triangle ΔCAD)
∠CED + ∠AEC = 180°(Sum of angles on a straight line)
Therefore ∠CED + 135° = 180°
∠CED = 180° - 135° = 45°
∠ECD + ∠CED + ∠CDA = 180°
Therefore ∠ECD = 180° - (∠CED + ∠CDA)
∠ECD = 180° - (45° + 25°) = 110°
Therefore, ∠ECD = 110°.
First, third, fifth, and sixth answer
3 yards by 9 yards is the original figure.
We can obviously say that the trapezoid falls into the Not Similar - Different Shape category since it is a trapezoid, and we were given a rectangle :P
The 6 yard by 3 yard falls into the category of Not similar - Different ratio of Side Lengths because the original was 9 yards by 3 yards. And one side remained the same while the other went larger, so they are not in a ratio.
The 2 yard by 8 yard falls into the category of Not similar - Different ratio of Side Lengths because 2 yards by 8 yards can be simplified in a ratio of 1 to 4 while the original is 3 to 9 or 1 to 3
The 6 yard by 18 yard falls into the category of Similar because 6 yards by 18 yards can be simplified in a ratio of 1 to 3 and the original is 3 to 9 which can be simplified to 1 to 3
The 9 yard by 8 yard falls into the category of Not similar - Different ratio of Side Lengths because 9 yards by 18 yards can be simplified in a ratio of 1 to 2 while the original is 3 yards to 9 yards or 1 to 3.
The 1 yard by 3 yard falls into the category of Similar because 1 yards by 3 yards can be simplified in a ratio of 1 to 3 and the original is 3 yards to 9 yards which can be simplified to 1 to 3
