in each of the following figures, establish that a pair of triangles is similar, and hence find x.
1. 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

6. 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

13. Sharon had a piece of rectangular construction paper 60 cm by 30 cm she cut five similar triangles away. the height of each triangle is half the breadth of the paper find the area of the remaining piece of paper
Jawaban:
The area of the remaining piece of paper is 1350 cm².
Penjelasan:
The area of the remaining piece of paper can be found by substracting the area of the rectangular construction paper by the total area of the cut.
Sharon cut away 5 triangles there, so the total area of the cut is 5 times the area of each triangle. The base of each triangle is:
60/5 = 12 cm
while its height is 15 cm.
Put those information into a formula:
A = A▭ – 5×A▽
A = (60×30 – 5×(1/2)×12×15) cm²
= (1800 – 450) cm²
= 1350 cm²
∴ Therefore, the area of the remaining piece of paper is 1350 cm².

19. Sharon had a piece of rectangular construction paper 60 cm by 30 cm she cut five similar triangles away. the height of each triangle is half the breadth of the paper find the area of the remaining piece of paper
Jawaban:
area triangel = ½ × 6 × 30 = 90cm²
5 triangels = 5 × 90 = 450 cm²
area ½ rectangular = 15 × 60 = 900 cm²
so, all area 450 + 900 = 1350 cm²
Penjelasan dengan langkah-langkah:
we can also use, area of 5 triangels is same of area ½ rectangular
area rectangular = 30 × 60 = 1800 cm²
area of 5 triangels= 5 × 90 = 450 cm²
so, all area = 1800 - 450 = 1350 cm²
sorry if the answer is false
