Pani-rosa [81]3 years ago

Answer:

x = 17.5 and y = 35

Step-by-step explanation:

2x + 10 = y + 10 ( alternate angles )

subtract 10 from both sides

2x = y ⇒ 6x = 3y → (1)

the sum of the 3 angles in the triangle = 180°

6x + y + 10 + 30 = 180 ( replace 6x by 3y )

3y + y + 40 = 180

4y + 40 = 180 ( subtract 40 from both sides )

4y = 140 ( divide both sides by 4 )

y = 35

substitute y = 35 into (1)

2x = 35 ( divide both sides by 2 )

x = 17.5

Solve x^2-11x=0, for x
ser-zykov [4K]

Start by factoring an x term out of the equation:

x(x-11)=0


Now, you can set each term equal to zero and solve for x:

x=0


x-11=0

x=11


x={0, 11}


Hope this helps!!
