Answer:

396 cm²

Step-by-step explanation:

Let us break this shape into two parts.

The left part:

27 cm² * 10 cm² = 270 cm²

The right part:

24 cm² - 10 cm² = 14 cm²

14 cm² * 9 cm² = 126 cm²

Total area:

270 cm² + 126 cm² = 396 cm²

Use a paragraph, flow chart, or two-column proof to prove the angle congruency. Given: ∠ CXY ≅ ∠ BXY

Llana [10]

Answer:

See explanation

Step-by-step explanation:

Consider triangles CAX and BAX. In these triangles,

$\overline{AC}\cong \overline{AB}$ - given
$\angle CAX\cong \angle BAX$ - given
$\overline{AX}\cong \overline{AX}$ - reflexive property

By SAS postulate, $\triangle CAX\cong \triangle BAX$

Congruent triangles have conruent corresponding parts. So,

$\overline{CX}\cong \overline{BX}$

Consider triangles CXY and BXY. In these triangles,

$\overline{CX}\cong \overline{BX}$ - proven
$\angle CXY\cong \angle BXY$ - given
$\overline{XY}\cong \overline{XY}$ - reflexive property

By SAS postulate, $\triangle CXY\cong \triangle BXY$

Congruent triangles have conruent corresponding parts. So,

$\angle XCY\cong \angle XBY$

PLEASE HALP I GIVE OUT BRAINLIEST

jekas [21]

Since there is two negative signs in the original equation, you need two negative signs in the equivalent one as well.

Because one of the negatives if before the fraction, it doesn't matter if the second negative is on the 13 or on the 12.

The answer is A.

2 25 divided by 11 10 in fraction

koban [17]

Answer:

$\frac{4}{55}$

Step-by-step explanation:

$\frac{2}{25} \div \frac{11}{10}$

$\frac{2}{25} \times \frac{10}{11}$

$\frac{2}{5} \times \frac{2}{11} = \frac{2 \times 2}{5 \times 11}$

$\frac{4}{5 \times 11}$

$= \frac{4}{55}$
