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:
31.5 square feet of counter top
Step-by-step explanation:
x represents the number of square feet
40x + 750 = 2010 subtract 750 from both sides
40x = 1260 divide both sides by 40
x = 31.5
118/13= 9 1/13
She will need 10 boxes. There will be 1 basketball in box 10.
1/4 = y/12
12/4 = y
y = 3
Answer: y = 3
Check work
1/4 = y/12
1/4 = 3/12
Correct!
Plug in 500 for h in the equation and you get:
e=3 (500)
e=1500
