2. the measures of three sides of a triangle are 9,16,20. determine whether the triangle is a right triangle. explain your answer..
i dont know what you say
3. the sum of three angles of triangle of 180 deg. the sum of two of the angles is equal to the third angle and the difference of the two angles is equal to 2/3 the third angles find the angles of this triangle?
suppose that :
x = first angle
y = second angle
z = third angle
The sum of three angles of triangle of 180°
So :
x + y + z = 180
The sum of two of the angles is equal to the third angle
So :
x + y = z
The difference of the two angles is equal to 2/3 the third angles
So :
x - y = (2/3) z
subtitute x + y = z
x + y + z = 180
z + z = 180
2z = 180
z = 180/2
z = 90
x + y = z
x + y = 90
x - y = (2/3) z
x - y = (2/3) (90)
x - y = 60 >>> x = 60 + y
subtitute x = 60 + y
x + y = 90
60 + y + y = 90
60 + 2y = 90
2y = 90 - 60
2y = 30
y = 30/2
y = 15
x = 60 + y
x = 60 + 15
x = 75
We got :
x = 75
y = 15
z = 90
So, the angles are 75°, 15°, and 90°
4. Triangle PQR and triangle DEF are similar. Which describes the relationship between the corresponding sides of the two triangles? * 2 points

5. The lenght of the legs of an isosceles triangle is 4 meters more than its base. If the perimeter of the triangle is 44 meter. Determine the lenghts of the sides of the triangle!bantuin plisss
Jawaban:
4meter x 44meter = 176 meter
Penjelasan dengan langkah-langkah:
Sisi x sisi x sisi
Isosceles triangle = segitiga sama kaki.parimeter = keliling
k= 44m..
kaki nya = 4cm lebih dari sisi bawah.
caranya
K = a + b + c
44 = (4+x) + (4+x) + x
44 = 8 + 3x
44-8 = 3x
36 = 3x
x = 36/3
x = 12
berarti sisi nya =
kaki = 12+ 4 = 16m
sisi bawah = 12m
ini ya kak jawabannya ..
6. Determine the length of the side of the right triangle labeled x.
please find the formula
okay actually it's not physics but math because it deals with cubes thanks
7. What is the sum of all angles of a triangle?
jumlah dari seluruh sisi dari segitiga adalah 3.
semoga membantu ^_^
8. the quadrilateral has two pairs of equal sides and four right angles(digambar)the quadrilateral has no equal sides and no equal angles(digambar juga)mohon cepet dijawab ya yg ngasal aku report
maaf kalau kurang rapih. Btw, kyknya lingkaran juga bisa buat yg kedua.
maaf kalau salah :)
9. Perimeter of a triangle is 217 cm.the ratio of the triangle sides are 5:9:17 find the length of each side of the triangle
Answer :
Known Values :
Perimeter (P) = 217 cm
Ratio of the sides = 5 : 9 : 17
First, find the value of each "1x" in the ratio ;
=> 217 cm : (5 + 9 + 17)
=> 217 cm : 31
=> 7 cm
Now, we can search each length of each side of the triangle according to the value of each "1x" we searched before.
"A" side :
=> 5 × 7 cm
=> 35 cm
"B" side :
=> 9 × 7 cm
=> 63cm
"C" side :
=> 12 × 7 cm
=> 84cm
So, we found the length for each side in the triangle are 35 cm, 63 cm, and 84 cm.

11. 4. Look at the following triangle! Every triangle holds the rule that the sum of the length of two sides is always greater than that of the third side. For the triangle ABC, AC + BC > AB. Form an inequality in x, and solve it!
Jawab:
x > 2
Penjelasan dengan langkah-langkah:
Dik:
AC = x - 3
AB = 12
CB = x + 11
inequality/pertidaksamaan:
AC + BC > AB
subtitusi nilai AC, AB, dan CB ke pertidaksamaan
(x-3) + (x+11) > 12
x - 3 + x + 11 > 12
2x + 8 > 12
2x > 12 - 8
2x > 4
x > 2
12. If the size of the angles of triangle are 3x°,4x°,5x°.the smallest angle of the triangle is
Jawaban Master Teacher
12x = 180°
x = 15°
smallest angle
3x = 45°13. 19. If the size of the angles of triangle are 3x°,4x° and 5xº. Then value of 4xºis ...
<A + <B + <C = 180°
3x° + 4x° + 5x° = 180°
12 x° = 180°
x= 180/12 = 15°
so, 4x° = 4(15)° = 60°
14. 18. If the size of the angles of triangle are 3x°,4x°and 5x°. The biggest angle of triangle is ...
sudut segitiga = 180°
3x° + 4x° + 5x° = 180°
12x = 180
x = 180/12
x = 15
sudut terbesar = 5x = 5 × 15 = 75°
15. yg bisa bantuin yakk.. the sum of the three angles of triangle is 180degree. the sum of the angle is equal to the third angle and the difference of the two angles is equal to 2/3 the third angle. find the angles of this triangle
Misalkan sudut A,B,C
A=B
A+B=⅔C
A+B+C=180
1:1:3=180
maka
2A+3A=180
5A=180
A=180/5
A=36
A+B+C=180
36+36+C=180
C=180-72
C=108
Jadi sudut A=36, B=36 dan C=108
16. In ABC triangle , the ratio of the sides is AB : BC : AC = 2 : 4 : 5. If the perimeter of the triangle is 44 cm, find the length of BC.
Jawab:
BC = 16 cm
