Answer
132 degrees
Step-by-step explanation:
Strategy: Find angle DEB and using that fact that DEB + DEF is 180 degrees to find angle DEF
The sum of the four angles of any quadrilateral is 360 degrees.
Since three angles are given, we can use that to find the fourth.
360-(147+93+72)=size of angle DEB. Solving, you get angle DEB is 48.
Also, knowing that segment BF is a straight line, it means that angle DEB + angle DEF is equal to a straight angle (180 degrees).
DEB+DEF=180
48+DEF=180
DEF=180-48=132 degrees.
Thus, angle DEF is equal to 132 degrees.
Answer:
estimate: $80
exact amount paid: $82
Step-by-step explanation:
If you round $246 to 240, then divide it by 3, you should get $80. The cost per pair should be around $80 each
For the exact answer you take the amount spent (246) and divide it by the amount of jeans she bought (3).
246/3 = 82
Answer:
the answer is 100m
Step-by-step explanation:
let 4:3 be 4x and 3x respectively
3x=75m
x=75÷3
x=25
Then,
4x=4*25
=100m
The values for y are as follows
4.5, 4, 3.5, 3, 2.5, 2
Answer:
a=3, c=-4, x=8
Step-by-step explanation:
5=4a-7
4a-7=5
4a=5+7
=12
a=12÷4
=3
3-8c=35
-8c=35-3
=32
c=-32÷8
=-4
-1/2x-7=-11
-1/2x=-11+7
=-4
x=4÷1/2
=4/1×2/1
=8
