Answer:
Parallel
Step-by-step explanation:
These 2 lines are parallel because they have the same slope (7).
Answer:
∠ABE and ∠CBD
∠ABC and ∠EBD
Step-by-step explanation:
we know that
<u>Vertical angle</u>s are a pair of opposite and congruent angles formed by intersecting lines
In this problem we have that
∠ABE=∠CBD ------> by vertical angles
∠ABC=∠EBD ------> by vertical angles
therefore
The angles that are vertical angles are
∠ABE and ∠CBD
∠ABC and ∠EBD
Given:
A circle of radius r inscribed in a square.
To find:
The expression for the area of the shaded region.
Solution:
Area of a circle is:
Where, r is the radius of the circle.
Area of a square is:
Where, a is the side of the square.
A circle of radius r inscribed in a square. So, diameter of the circle is equal to the side of the square.
So, the area of the square is:
Now, the area of the shaded region is the difference between the area of the square and the area of the circle.
Therefore, the correct option is (a).
The terms of this expression would be 8x,-20y, and -10. The coefficients are the numbers in front of the variable so they would be 8 and 20 because they are accompanied by a variable.
Answer:
Step 3
Step-by-step explanation:
7( 8.5-1.5) +8 ÷2
PEMDAS
Parentheses
7*7 +8 ÷2
Then multiplication and division from left to right
49 +8 ÷2
We are still on multiplication and division
49+4
So step 3 is the first mistake
