Answer:
7.722cm^2, x=129
Step-by-step explanation:
12*12=144- area of the whole square
the diameter for the circle is 12
radius is 6
Area for circle= pi* r²
3.142*6^2=113.112
144-113.112=30.888
30.888/4=7.722
Answer: E
Step-by-step explanation: An integer is a whole number ( that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and -3. Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, . 09, and 5,643.1.
Answer:
angle b = 40 degrees
Step-by-step explanation:
Because angle a + angle b = 90 degrees
50 + angle b = 90
angle b = 90 - 50 = 40 degrees.
Answer:
1. B. By the vertical angles theorem.
2. ∠BED
Step-by-step explanation:
We have that, AB || CD and the two lines in between them are intersecting each other.
Since, we know that,
<em>Vertical Angles Theorem states that 'Two opposite angles of the intersecting lines are congruent'.</em>
So, as the lines are intersecting, we get by 'Vertical Angles Theorem',
∠AEB ≅ ∠CED and ∠AEC ≅ ∠BED.
