liq [111]2 years ago
3 0

Answer:

  • We know : The exterior angle is equal to the sum of two non-adjacent interior amhles. Set up an equation and solve for x :

\longrightarrow \tt5x + 10 = 3x + 3x

\longrightarrow \tt \: 5x  + 10= 6x

\longrightarrow \tt10 = 6x - 5x

\longrightarrow \tt \: 10 = x

Replacing value :

✯\tt m \:  \angle \: \: BCD = 5 \times 10 + 10 =  \boxed{ \tt{60}}

  • Our Final answer is 60 .

Determine which of the following ordered pairs satisfies the given system of equations.
alekssr [168]

Answer:

(-3,2)

Step-by-step explanation:

1) -2x+y=8

you need to leave the Y alone on one side. Then, the term -2x goes to the other side with its opposite sign which is +.

y=8+2x

2) y=2x/(5-8)

3) 8+2x=2x/(5-8)

now, you need the x value. for that, you need to leave x alone on one side.

8+2x=2x/(-3)

8+2x=-(2/3)x

8=-(2/3)x-2x

8=-(8/3)x

8/-(8/3)=x

-3=x

4) you now have the x value. you need the y value. for that, replace the x in one of the given equations. let´s use the 1st equation.

-2x+y=8

y=8+2x

y=8+2*(-3)

y=2

result:

x= -3

y=2
