Answer:

The figure WXYZ illustrates a rhombus, where angle 1 is 25°.

As angles 1 and 2 are adjacent to each other.

Given that the opposite sides of a rhombus are parallel.

The sum of adjacent angles in a rhombus is supplementary.

→1 + 2 = 180°

→25° + 2 = 180°

→2 = 180° - 25°

→2 = 155°

3. Terdapat dua bidang saling berpotongan dan tidak berhimpitan maka
Svet_ta [12734]

Kelas: VII (1 SMP)

Materi: Geometri

Kata Kunci: Garis, Sisi, Rusuk, Bidang

Pembahasan:

Suatu titik dalam geometri adalah elemen paling dasar, menunjukkan posisi yang tidak memiliki ukuran (nol panjang, nol lebar, dan nol tinggi) dan dilambangkan dengan huruf kapital.

Garis terdiri dari kumpulan titik yang memanjang tanpa batas di kedua arah.

Ruas garis adalah bagian dari garis yang terdiri dari dua titik ujung dan dinamai menurut kedua titik tersebut.

Sinar garis adalah segmen dari garis dengan hanya satu titik ujung. Dinamai berdasarkan titik ujung dan titik lain di sepanjang sinar tersebut.

Sudut terbentuk dari dua sinar yang memiliki titik ujung yang sama yang dikenal sebagai titik sudut; sinar-sinar tersebut disebut sisi-sisi sudut.

Bidang terdiri dari titik-titik tak terhingga yang membentuk permukaan datar dan meluas tanpa batas. Memiliki panjang dan lebar tak terhingga, tetapi tinggi nol. Bidang biasanya ditunjukkan dengan gambar segi empat dan dinamakan dengan huruf besar.

Rusuk adalah garis hasil pertemuan dua sisi pada bidang.

Dua bidang dapat dikatakan berpotongan jika ada garis potong antara keduanya.

Bidang sejajar apabila tidak ada garis perpotongan yang terbentuk di antara keduanya.

Dua bidang disebut berhimpitan jika semua titik terletak pada keduanya.

Mari kita analisa soal ini.

Apabila dua bidang saling bersilangan dan tidak berhimpit, maka perpotongan mereka akan membentuk garis.

Oleh karena itu, jawabannya adalah B.

Semangat!

(Please Hurry!) Which expression is equivalent to the following complex fraction?
lawyer [12517]

Answer:

The equivalent expression for the provided complex fraction is

\frac{-2x+5y}{3x-2y}

Step-by-step explanation:

To simplify the complex fraction, calculating the numerator and denominator individually is effective.

Numerator:

\frac{-2}{x} + \frac{5}{y}\\ = \frac{-2y + 5x}{xy}

Denominator:

\frac{3}{y} + \frac{-2}{x}\\ = \frac{3x - 2y}{xy}

Resolving the complex fraction:

[\frac{-2}{x} + \frac{5}{y}] / [\frac{3}{y} + \frac{-2}{x}]\\= [\frac{-2y + 5x}{xy}] / [\frac{3x - 2y}{xy}]

=\frac{-2y + 5x}{xy} * \frac{xy}{3x - 2y}

Common terms in the numerator and denominator will cancel out (Cross multiplication):

= \frac{-2y + 5x}{3x - 2y}

The partial factorization of x2 – x – 12 is modeled with algebra tiles. An algebra tile configuration. 4 tiles are in the Factor
Svet_ta [12734]

Response:

Stepwise explanation:

Given the expression

x² - x - 12

First, let’s factor this expression

Refer to the attachment for simplification

x² - 4x + 3x - 12

x(x - 4) + 3(x-4)

(x + 3)(x - 4)

Consequently, 4 negative unit tiles are necessary
