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%

4. 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
5. Find length x in the right-angled triangles to 3s.f

6. 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).

7. 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
8. in rectangle PQRS PQT and TRV are triangles PQ = 12cm QT = 10cm TR = 5cm and SV = 3cm Find the shaded area
Jawab:
97,5 cm²
Penjelasan dengan langkah-langkah:
Luas yang diarsir
(PQ x QR) - PQT - TRV
( 12x 15) - 1/2 (12x10) - 1/2 (5x9)
180 - 60 - 22,5 = 97,5 cm²
9. In the figure below, the two triangles are similar. What is the value of x? *
5 : 6 = 11 : x
5x = 66
x = 66 : 5
x = 13,2
10. in each of the following figures, establish that a pair of triangles is similar, and hence find x.
Jawab:
a. x = 8 cm
b. x = 15/4 cm
c. x = 24/5 cm
Penjelasan dengan langkah-langkah:
a. 3/4 = 6/x
x = 4(6)/3 = 24/3
x = 8 cm
b. 3/x = (3+1)/5
3/x = 4/5
x = 3(5)/4
x = 15/4 cm
c. 3/5 = x/(3+5)
3/5 = x/8
x = 3(8)/5
x = 24/5 cm

12. 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
13. Use pythaporus'theorem to find the length of the hypotenuse in these right-angled triangles 8 6
Jawaban:
8 sorry kalo salah
Penjelasan dengan langkah-langkah:
maaf sekali lagi Im sorry
14. 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

17. ABCD is a rhombus. BEF and CEF are isosceles triangles. BE = EF and CE = CF. ACG, DCE and BCF are straight lines. (a) Find LABC. (b) Find ZBEC.
Jawab:
(a) Since ABCD is a rhombus, all its sides are equal. Therefore, LABC = LADC. Also, the opposite angles in a rhombus are equal. Thus, LABC = LADC = 180 - LDCB (since the sum of angles in a quadrilateral is 360 degrees). Therefore, LABC = (180 - LDCB)/2.
(b) Since BEF and CEF are isosceles triangles, ZBFE = ZEBF and ZECF = ZEFC. Moreover, the sum of angles in a triangle is 180 degrees. Therefore, ZBEC = ZEBF + ZEFC = ZBFE + ZEFC = (180 - ZBEF)/2 + (180 - ZCEF)/2 = 180 - (ZBEF + ZCEF)/2.
