3. Painted on a wall are 4 red triangles, 2 blue triangles, 6 green triangles and 8 yellow triangles. What percentage of the triangles are blue or red?
Jawaban:
red : 20%
blue : 10%
Penjelasan dengan langkah-langkah:
4+2+6+8=20
red : 4/20=2/10=20%
blue : 2/20=1/10=10%
semoga membantu.
Penjelasan dengan langkah-langkah:
4 merah
2 biru
6 hijau
8 kuning
berjumlah = 20 segitiga
segitiga biru dan merah = 4+2 = 6
20 = 100%
1 = (100/20)%
1 = 5%
presentase segitiga biru dan merah :
= (5×6)%
= 30%

jangan lupa follow hehe
4. Characteristics of Triangles and Quadrilaterals is?
Jawaban:
triangle is a simple closed curve or polygon which is created by three line-segments. In Euclidean geometry, any three points, specifically non-collinear, form a unique triangle and separately, a unique plane (known as two-dimensional Euclidean space).

5. A pattern has 12 blue triangles to every 16 yellow triangles. what is the ratio of yellow triangles to the blue triangles ?
total = 16 + 12 = 28
blue triangles = 12/28
= 3/7
yellow triangles = 16/28
= 4/7
ratio yellow to the blue triangles = 3/7 : 4/7
= 3/7 × 7/4
= 3/4
dont forget to make the smartest answer oke.
thanks

8. these two quadrilateral are congruent
Penjelasan dengan langkah-langkah:
If a quadrilateral is a parallelogram, then consecutive angles are supplementary. If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If one pair of opposite sides of a quadrilateral are parallel and congruent, then the quadrilateral is a parallelogram.
9. 10. Let A = {right-angled triangles). (a) Is each of the following triangles an element of A? Explain your answer. (i) triangle with sides 3 cm, 4 cm and 5 cm (ii) triangle with sides 2 cm, 2 cm and 3 cm (b) Can each of the following sets be the universal set for the set A? Explain your answer. (i) U = {all triangles} (ii) V = {all polygons}
Problem9
Let
[tex] \xi = \{x \colon x \text{ is an integer and } -3 \le x \le 3 \} \\ [/tex]
[tex] A = \{x \colon 2x + 1 < 5 \} \\ [/tex]
[tex] B = \left \{ x \colon \frac{x}{3} \text{ is an integer} \right \} \\ [/tex]
(a) Express the set [tex] A [/tex] by listing its elements.
(b) Is [tex] -4 [/tex] an element of [tex] A [/tex]? Explainyour answer.
(c)Write down the common elements of [tex] A [/tex] and [tex] B [/tex].
Solution
For part (a), the set of [tex] A [/tex] can be written as
[tex] A = \{-5, -3, -1, 1, 3 \} [/tex]
For part (b), [tex] -4 [/tex] is not an element of a set of [tex] A [/tex] because [tex] A [/tex] is a set of odd numbers with [tex] x \in [-3, 1], x \in \mathbb{Z} [/tex].
For part (c), both sets can be written as
[tex] A = \{-5, -3, -1, 1, 3\} [/tex]
[tex] B = \{-1, 0, 1\} [/tex]

11. Nomor 4 please , buat homework besok
Jawab:
4a. 6
4b. 3
Penjelasan dengan langkah-langkah:
f(x) = ⅓(x)+5
4a.
f(3)= ⅓(3)+5
= 1+5
= 6
4b.
f(-6)= ⅓(-6)+5
= -2 + 5
= 3
Penjelasan dengan langkah-langkah:
[tex]f(x) = \frac{1}{3} x + 5[/tex]
[tex]f(3) = \frac{1}{3} .3 + 5 \\ f(3) = 1 + 5 \\ f(3) = 6[/tex]
[tex]f( - 6) = \frac{1}{3} .( - 6) + 5 \\ f( - 6) = - 2 + 5 \\ f( - 6) = 3[/tex]
12. MNO and MPO are isosceles triangles. Find t
Jawaban:
maksudnya apaan kak aku gk paham
13. Find the unknown marked angle in each of the Isosceles triangles.
karena DF dan EF sama panjang, maka sudut D dan sudut E sama besar.
EF = DF = 53°
Untuk menghitung sudut F maka
180° - 53° - 53° = 74°
Semoga membantu ;)
14. A pattern has 12 blue triangles to every 16 yellow triangles. what is the ratio of yellow triangles to the blue triangles ?

17. A pattern has 5 blue triangles to every 80 yellow triangles. What is the ratio of blue Inangles to all triangles?
All triangles = 5 + 80 = 85
The ratio of blue : all triangles
= 5 : 85
Divide each by 5
= 1 : 17
18. cara bukti in itu congruent gimana ( tolong di jabarin ya jelasin nya )
gambarnya kan sama (sebangun) kemudian ukurannya juga sama, maka gambar tersebut dikatakan kongruen
