OK, so;
BDE and BED are congruent because the opposite sides are both congruent
To find BDE and BED you must subtract 66 degrees from 180 degrees.
You are then left with 114 as the sum of both the angles you need to find
Since they are congruent, all you need to do is divide by two
114/2=57 degrees for both BDE (a) and BED(b)
Now for angle A and C;
This is easy because they are both congruent to the first two!
So basically, all of question four is "57 degrees"
Sadly for number 5 i did not understand the question :"(
For 6 tho;
AC is parallel to DE because angle C is congruent to angle BED
All the others can be ruled out
For 7;
BD is half the length of AE, so:
4x+20=2(3x+5)
4x+20=6x+10
20=2x+10
10=2x
x=5
This means BD is 20 bc
3(5)+5
15+5
20
And AE is 40 bc
20X2=40
or...
4(5)+20
The answer would be -13 54/55
38.1 seconds I believe simply divide 4m/s into 152.4 m and you will have 38.1 seconds
A would be the correct answer hope this helps
Answer:
The work space in Elisha's room has a width of 1/2 meter and an area of 3/5 square meter. How long is it?
Step-by-step explanation:
In this, width of the room is given and the area is given. We have to find the length.
To find the length, area should be divided by width.
ie. 3/5 divided by 1/2
