You know angles B and C are both 60°, the values of the angles in an equilateral triangle. Since the sum of angles in a quadrilateral is 360°, you have
B + C + x + y = 360°
60° +60° + x + y = 360°
x + y = 240°
Answer:
6300
Step-by-step explanation:
Answer:
39
Step-by-step explanation:
(15 / 5)+9+(14 - 5 )*3
So basically all your doing is substituting the given number to the equation:
(3, ) (,0)
y=8(3)+2. 0=8x+2
y=24+2. 8x=0-2
y=26. 8x= 2
divide both side by 8
x=4
(3,26) (4,0)
