Options are:<br><br> X=2, y=3<br><br> X=3, y=2<br><br> X= -2, y=3<br><br> X=4, y=8
trapecia [35]

Step-by-step explanation:

2x - 5 = y - 5

2x = y

x = y/2

y - 3 = x + 1

Substitute the value of x here,

y - 3 = \rm{\dfrac{y}{2} + 1}

y - 3 = \rm{\dfrac{y + 2}{2}}

2y - 6 = y + 2

y = 8

Now, x = 8/2

x = 4

So, go for D part, it is the correct answer.

Good Night/Day !

Each regular polygon has radil and apothem as shown. Find the measure of each numbered angle. ​
ruslelena [56]

Answer:

∠5 = 60°

 ∠6 = 30°

 ∠7 = 120°

Step-by-step explanation:

Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)

 ∠5 = 60°

 ∠6 = 30°

 ∠7 = 120°
