Step-by-step explanation:
∠CBA = ∠BAG = 28° ( Alternate angles )
∠EAD = 90° - ∠BAG = 90° - 28° = 62° ( ∠EAG is right )
∠EDB is an external angle of ΔADE
• The external angle is equal to the sum of the 2 opposite interior angles
∠EDB = x + 4x = 5x
5x = 3x + 62 ( subtract 2x from both sides )
2x = 62 ( divide both sides by 2 )
x = 31, hence
3x = 3 × 31 = 93° and 4x = 4 × 31 = 124°

Rewrite 42 as 42.0 and act like it is a question of division of 420 by 241. do with long division as usual, but at the end make sure to place a decimal point at the same position
Answer:
.75 x 10 = $7.5
.25 x 30 = $7.5
They have the same amount so Noah is right

Answer: The answer is 148 square feet.
Step-by-step explanation:
So if we are given the information to the area of the composite figure, we just first have to find the area of the smaller shapes and then add them all together to achieve the total.
1. The larger rectangle is a 10 by 14 rectangle.
2. The smaller rectangle is a 1 by 8 rectangle.
How did I get around to 8 feet?
Subtract 3 and 3 from 14, and you'll get 8 for the side.
Now just find the areas of each of the rectangles:
1. 10 times 14 = 140
2. 1 times 8 = 8
Now add them together:
140 + 8 = 148
The answer is 148 square feet.
