Actually welcome to the concept of the Angle sum property...
The Angle sum property of a Quadilatetal =》
m/_A + m/_B + m/_C + m/_ D = 360°
Thus adding all the angles we get as....
=》 X + X + X+ 15° + X + 45° = 360°
=》 4X + 60° = 360°
thus ..4X = 360 - 60 = 300
Thus .. 4X = 300
X = 300 ÷ 4 =》 75°
X = 75°
Answer:
The above has one solution

Answer:
The Answer is that one box of Oranges costs $7.13 and one box of Apples costs $12.99.
Step-by-step explanation:
Let o = oranges and a = apples
Equation 1:
3o + 14a = 203
Solve for o:
3o = 203 - 14a
o = 203/3 - 14/3a
o = 67.66 - 4.66a
Equation 2:
11o + 11a = 220
Substitute:
11(67.66 - 4.66a) + 11a = 220
744.26 - 51.26a + 11a = 220
-40.26a = 220 - 744.26
-40.36a = -524.26
a = -524.26/-40.36 = $12.99 for a box of Apples
Solve for oranges, o:
o = 67.66 - 4.66a
o = 67.66 - 4.66(12.99)
o = 67.66 - 60.53 = $7.13 for a box of Oranges
Hope this helps!! Have an Awesome day!!! :-)

Step-by-step explanation:
10 is the length 5 is the length and width
Answer:
The length of rectangular plot of land is 160 ft.
Step-by-step explanation:
L = 2 W (the length is twice the width)
P = 480 ft. (perimeter of rectangular plot of land)
L = ?
2. 2W + 2W= 480 ft >>> (2 times twice width=L) + 2W=480 ft.
4W + 2W= 480 ft >>>> 6W= 480 ft.
W= 80 ft.
L = 2. 80 = 160 ft. (Length is twice the width)
P= 2L + 2W (formula for the perimeter)
2. 160 + 2. 80 = 480 ft.
