The way to handle this is to realize that the 180 degree angle (the two supplementary angles added together to make 180o by definition) is actually divided into 6 parts. There are 2 parts for the smaller angle and 4 for the larger.
Added together the 2 angles = 180
Equation
Let one of the 6 parts = x
2x + 4 x = 180
Solve
2x + 4x = 180 Add the like terms on the left together.
6x = 180 Divide by 6
x = 180/6
x = 30
Answer
Since one angle is 2 parts (the smaller angle)
2 * 30 = 60
And the larger angle is
4 * 30 = 120
The two angles are
60,120 <<<< answer.
Further comment.
The two angles are supplementary 60 + 120 = 180
One angle is twice as big as the other. 2*60 = 120
Answer: 138.63 mm²
Step-by-step explanation:
First, we will solve for the area of the rectangle.
A = L * W
A = 15 mm * 5 mm
A = 75 mm²
Next, we will solve for the area of the semi-circles. Since there are two equivalent semi-circles, I will find the area of one circle with the same radius as these two.
First, we need to find the radius.
15 mm - 3 mm - 3mm = 9mm, 9 mm / 2 = 4.5 mm
A = πr²
A = π(4.5)²
A ≈ 63.62 mm²
Lastly, we will add them together.
75 mm² + 63.62 mm² = 138.63 mm²
