2xy=2*3*5= 30
It essentially means 2(3)(5) so you just multiply it all together.

△QRS is rotated about point P to △Q′R′S′ .
Sedbober [7]

Answer:

As Given △QRS is rotated about point P to △Q′R′S′ .

As we know after rotation by any angle of pre-image neither the shape nor size of the image changes, the image after rotation is congruent to pre image.

Out of the options given

→The corresponding lengths, from the point of rotation, between the pre-image and the image are preserved.

→The corresponding angle measurements in each triangle between the pre-image and the image are preserved.

are true.

The dotted line represents the mid segment of the trapezoid. Find the value of X
Ganezh [65]

<u>Given</u>:

Given that the bases of the trapezoid are 21 and 27.

The midsegment of the trapezoid is 5x - 1.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the trapezoid midsegment theorem.

Applying the theorem, we have;

Midsegment = \frac{b_1+b_2}{2}

where b₁ and b₂ are the bases of the trapezoid.

Substituting Midsegment = 5x - 1, b₁ = 21 and b₂ = 27, we get;

5x-1=\frac{21+27}{2}

Multiplying both sides of the equation by 2, we have;

2(5x-1)=(21+27)

Simplifying, we have;

10x-2=48

Adding both sides of the equation by 2, we get;

10x=50

Dividing both sides of the equation by 10, we have;

x=5

Thus, the value of x is 5.
