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?
1. 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%
#cmiww
jangan lupa follow hehe
2. Tolong artikan the following figures are not drawnmto scale . Identify and shade the right-angled triangles
bentuk-bentuk di bawah ini tidak digambar sesuai dengan skala
identifikasi dan arsir segitiga-segitiga dengan sisi/sudut yang tepat :)

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
6. How many the Kay concepts of trigonometry?Tell and give 2 Example of each
Jawaban:
There are six fundamental concepts of trigonometry: triangles, right triangles, angles, angle measure, trigonometric functions, and trigonometric identities.
Example 1 - Triangles: A triangle is a three-sided polygon with three angles.
Example 2 - Right Triangles: A right triangle is a triangle with one 90 degree angle.
Example 1 - Angles: An angle is formed by two lines that intersect at a given point.
Example 2 - Angle Measure: Angle measure is the measurement of an angle in terms of degrees or radians.
Example 1 - Trigonometric Functions: Trigonometric functions are mathematical equations that describe a relationship between angles and sides of a triangle.
Example 2 - Trigonometric Identities: Trigonometric identities are relationships between trigonometric functions that hold true for all angles.

9. Find the unknown marked angles in each of the right-angled triangles.tolong bantu dong
Jawab:
a. 180° - (90° + 57°)
180° - 147°
= 33°
b. ∠ABC = 180° - (90° + 28°)
= 180° - 118°
= 62°
∠ADC = 180° - {90° - (90° - 28°)}
= 180° - (90° + 62°)
= 180° - 152°
= 28°
c. ∠GEF = 180 - (90 + 26)
= 180 - 116
= 64
∠DEG = 90 - 64
= 26

11. A pattern has 12 blue triangles to every 16 yellow triangles. what is the ratio of yellow triangles to the blue triangles ?
Penjelasan dengan langkah-langkah:
12 di bagi 2 sama dengan 6
16 di bagi 2 sama dengan 8
jadi perbandingan nya adalah 6 banding 8
12. 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]

19. 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).
