Answer: 198 is your answer:65+66+67 = 198 Hope I helped!
Step-by-step explanation:
The area of the circle will be 28.27 km.
Answer:
For the first one:
D) The perpendicular bisector of line MN
For the second one:
You need a protractor (angle ruler) to measure the angle. After finding the measurement, divide it into two. After finding the result, find the point that has that angle.
Example -
The pie measures 120°.
120° ÷ 2 = 60°
Find the point that measures 60° and connect the points (from the start to the edge of the pie).
For the third one:
C) m∠ABD ≅ m∠CBD
The difference between an algebraic expression and a numerical expression is that algebraic expressions contain numbers and variables. Numerical expressions only contain numbers.
Ex:
Algebraic Expression- 5x+9
Numerical Expression- 4+2
