1. 1.) Triangle MNO is a right-angled triangle and triangle NOP is an isosceles triangle. MO is perpendicular to OP. ∠OMN = 53°. Find ∠OPN.
Penjelasan dengan langkah-langkah:
< MON = 90-53= 37°
< NOP = 90-37= 53° = < PNO
=> <OPN=180-(53+53)
=180-106=74°

7. Triangle ADB is an equilateral triangle. BCD = 54º and AB isperpendicular to BC. Find ADC.
Penjelasan:
ABD = BDA = DAB
ABD = 180° / 3
ABD = BDA = 60°
ABC = ABD + DBC
DBC = ABC - ABD
DBC = 90° - 60°
DBC = 30°
BDC = 180° - 30° - 54°
BDC = 96°
ADC = ADB + BDC
ADC = 60° + 96°
ADC = 156°

11. Triangle ABC is similar to triangle XYZ. What is the length of segment BC? * 2 points
Artinya segitiga ABC sebangun dengan segitiga XYZ
Jadi untuk mencari panjang/length of BC
Dengan menggunakan rumus perbandingan
12/x=8/6 (tukar tempat/switch places)
8x = 12 × 6
8x = 72
x = 72/8
x = 9 cm
So the length of segment BC its 9cm
Jadi panjang BC adalah 9cm

18. The area of a triangle is 528cm2. the length of its base is 33cm. calculate the perpendicular height of the triangle.
Diketahui:
Luas segitiga = 528 cm²
Panjang alas = 33 cm
Tinggi = ?
[tex]luas \: = 528 \\ \frac{1}{2} \times a \times t = 528 \\ \frac{1}{2} \times 33 \times t = 528 \\ t = \frac{528 \times 2}{33} \\ t = 32[/tex]
Jadi, tinggi segitiga adalah 32 cm.
Jawab:
32
Penjelasan dengan langkah-langkah:
L=528
a= 33
L= a*t/2
528= 33*t/2
1056=33t
t= 1056/33
t=32

360 : 2 = 180 cm²
maaf kalo salah ^_^
Pythagorean Theorem"In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides".
Question:
The perimeter of an isosceles triangle is 36 cm. If the base is 10 cm of length, the area of the triangle is ... cm²
Step by step:
Isosceles triangle have 36 cm of its perimeter. The perimeter of triangle is calculated by sum of each side.
Finding length of each leg (x):
36 cm = 10 + x + x
36 = 10 + 2x
26 = 2x
x = 13 cm.
To find the height of triangle, use pythagorean theorem. Let height is written by "y".
[tex]\displaystyle\\y = \sqrt{13^2 - 5^2}\\\\y = \sqrt{169 - 25}\\\\y = \sqrt{144}\\\\y = 12~\text{cm}[/tex]
Calculate the area:
[tex]\text{Area of triangle:}\\\\\boxed{\frac{\text{base}\times\text{height}}{2}}[/tex]
[tex]\displaystyle= \frac{10 \times 12}{2}\\\\= \frac{120}{2}\\\\= 60~\text{cm}^2[/tex]
Conclusion:
The area of an isosceles triangle with 10 cm length of base and 36 cm of its perimeter is 60 cm²
