Ty is right inches taller than his brother Reece if ty is 42 inches tall how tall is Reece. Write an equation using a variable r?

12/5.79=1/x

12x=5.79(1)

12x=5.79

[divide 12 on both sides]

x=193/400(0.4825)

Hello there! :)

Vertical angles are congruent, therefore:

∠A ≅ ∠B

3x - 30 = 2x - 9

Subtract 2x from both sides:

3x - 2x - 30 = 2x - 2x - 9

x - 30 = -9

Add 30 to both sides:

x - 30 + 30 = -9 + 30

x = 21.

Answer:

x = 21

Step-by-step explanation:

Vertical angles are congruent, thus

∠ A = ∠ B , substitute values

3x - 30 = 2x - 9 ( subtract 2x from both sides )

x - 30 = - 9 ( add 30 to both sides )

x = 21

Answer:

To find the coordinates of x, we can use the midpoint formula, which says that the midpoint of a line segment is the average of the x-coordinates and the y-coordinates of the endpoints12. That is:

m=(2x1​+x2​​,2y1​+y2​​)

In this case, we know that m is (−3,−1) and y is (−8,6). We can plug these values into the formula and solve for x:

(−3,−1)−3−6x−1−2−8​=(2x+(−8)​,2−1+6​)=2x−8​=x−8=2=2−1+6​=−1+6=6​

Therefore, x is (2,−8). You can check your answer by plugging it back into the midpoint formula and see if you get m.

I hope this helps
