<u>Definition: </u>Vertical angles are the angles opposite each other when two lines cross.
By the definition options
- they are formed by intersecting lines,
- they are opposite to each other
are true.
Vertical Angles Theorem states that vertical angles are congruent. Thus, option
is true.
Option
- they are always supplementary
is false, because supplementary are angles that add up to 180°, but vertical angles can have different measures which do not add up to 180°.
Answer: a) The percent of change in perimeter is 100%.
b) The percent of change in area is 300%.
Step-by-step explanation:
Since we have given that
if the side lengths of rectangle get doubled.
Let the length be 'x'.
Let the breadth be 'y'.
So, Perimeter of rectangle would be
Area of rectangle would be
After doubling the lengths,
Length becomes '2x'.
Width becomes '2y'.
So, perimeter becomes
Area becomes
a. Find the percent of change in the perimeter.
Hence, the percent of change in perimeter is 100%.
b. Find the percent of change in the area.
Hence, the percent of change in area is 300%.
Answer:
B. and D.
Step-by-step explanation:
Answer: 6000+200+10+9
Step-by-step explanation:
The ones place multiplies by 1 so 9*1=9
The tens place multiplies by 10 so 10*1=10
The hundreds place multiply by 100 so 100+2=100
The thousands place multiply by 1000 so 1000*6=6000
