Please help me i will give brainliest

Mathematics
1 answer:
Irina-Kira [14]2 years ago
5 0

Answer:

Look below

Step-by-step explanation:

We know QS is parallel to RT, so that will be the first one. We also know that r is congruent to s, so add that if possible

Next, we have to use the alt. int. angles are congruent theorem, so we can say that angle QTR and angle SOT are congruent due to this rule.

Next we have to use reflexive property, and the only thing that fits is the transversal intersecting the parallel lines. So we can say that QT is congruent to TQ.

Then we can say that triangle SQT and triangle ROT are congruent due to SAS.

Finally, we can say angle QTS is congruent to angle TQR because of corresp. parts of congruent triangles are congruent(CPCTC for short)

I hope this helped!

It would be greatly appreciated if you marked this answer as brainliest!

In the diagram, the length of segment BC is 23 units,
SIZIF [17.4K]

Answer:

The length of segment DC 33 units.

Step-by-step explanation:

Given:

The length of segment BC is 23 units.

To find:

Length of segment DC=?

Solution:

AB = 2x + 7

From the figure ,AB = BC

2x + 7 = 23

2x = 23 - 7

2x = 16

x = 8

In the Δ ABD and ΔCBD

(1) AB = BC(As given in the figure.)

(2) ∠DBA = ∠DBC = 90°

(3) BD = BD(Common side of both the triangle.)

Thus by using SAS congurence property .

Δ ABD ≅ ΔCBD

Thus AD = DC(Corresponding sides of the congurent triangle.)

Thus AD = 4x + 1

Substituting  x = 8

AD = 4 \times 8 + 1

AD = 32 + 1

AD    = 33 unit

Thus AD = DC = 33 unit

Find the area of the shaded region.​​
earnstyle [38]

There are four parts of a circle, so you have to find out the area of the circle:-

10 cm=Radius

10^{2}=100

\pi=3.14

3.14*100=314 cm^{2}

Now, find the area of the square box:-

Since half the side of the square is 10 cm, the total length of one side is 2*10 which is 20 cm.

Area=S*S

=20*20=400 cm^{2}

Now subtract the area of the box from the area of the square:-

400-314= 86 cm^{2}

That is the area of the shaded part.

Happy to help you!

Measure the area for each rectangle listed.
Rzqust [24]

EFHG => EF = AC = 3cm and EG = AB = 10cm, so the area = 3*10 = 30 cm^2

ACFE =>  AC = 3cm and FC = 2cm, so the area = 3*2 = 6 cm^2
