Answer:
The sum of two angle is 180 (supplementary)
given angle = 3:1
first angle =3x
2 nd angle=1x
3x+1x =180
4x =180
x = 180/ 4
x = 45
so first angle =3x x = 45
= 3×45
= 135 degree
2nd angle = 1x
=45 degree
ans
Both angles are 135 and 45

Answer: Its C
Step-by-step explanation:
24 + 25 + 26 + 27 + 28 + 29 + 30 + 31 + 32 + 33 + 34 ÷ 11 = 29
Answer:
c
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Set 1
sum = (2 × 27) + (2 × 28) + (3 × 29) + (2 × 30) + (1 × 33)
= 54 + 56 + 87 + 60 + 33 = 290
The count is 10 ( number of dots ), then
mean = [tex]\frac{290}{10}[/tex] = 29
Set 2
sum = (4 × 24) + (4 × 25) + (2 × 27)
= 96 + 100 + 54 = 250
The count is 10 ( number of dots ), then
mean = [tex]\frac{250}{10}[/tex] = 25

David's money is three times Siti's money. Farid has RM 150 less than Siti. The total amount of their money is RM 2 000. How much do each of them have?
Answer:
Siti's money = RM 430
David = RM 1,290
Farid = RM 280
Step-by-step explanation:
Let
Siti's money = x
David = 3x
Farid = x - 150
Total of their money = RM 2 000
x + 3x + (x - 150) = 2000
4x + x - 150 = 2000
5x = 2000 + 150
5x = 2,150
x = 2,150/5
x = RM 430
Siti's money = x
= RM 430
David = 3x
= 3(430)
= RM 1,290
Farid = x - 150
= 430 - 150
= RM 280

take x =initial deposit amount. then make equation:
x+75.5+55.25-25.15-18.65 = 210.85
simplify:
x+86.95 = 210.85
x=210.85 - 86.95
x=123.90
so Initial deposit amount is $123.90
check: 210.85+18.65+25.15-55.25-75.5 = 123.9
123.9 = 123.9

Un rectángulo de 72 metros cuadrados de área y 18 m de base ¿Cuánto mide de altura?
Answer:
Step-by-step explanation:
área = base multiplicada por altura
72 m² = 18 m × altura
Altura = 72/18 = 4 m

Construct an isosceles right-angled triangle ∆PQR where ∠
Answer:
Please find attached the required triangle drawn with Microsoft Visio
Step-by-step explanation:
The isosceles triangle ΔPQR we are to construct has the following parameters;
∠PQR = 90°
Length of side hypotenuse PR = 4 cm
Therefore, given that the triangle is right triangle is an isosceles triangle the length of each of the side legs are equal
Therefore, we have;
Length of PQ = Length of QR
The length of the legs , [tex]\overline {PQ}[/tex] and [tex]\overline {QR}[/tex], are given by Pythagoras's theorem as follows;
[tex]\overline {PR}[/tex] = √([tex]\overline {PQ}[/tex]² + [tex]\overline {QR}[/tex]²) = √([tex]\overline {PQ}[/tex]² + [tex]\overline {PQ}[/tex]²) = [tex]\overline {PQ}[/tex]·√2
∴ [tex]\overline {PQ}[/tex] = 4 cm/(√2) = 2·√2 cm = [tex]\overline {QR}[/tex]
The required triangle drawn with Microsoft Visio is attached

The diagram shows the position
of three towns represented by
letters A, B and C.
B is 7 km from A on a bearing of 037°
C is 8 km from B on a bearing of 140°
Find the bearing of C from A.
Give your answer correct to 1 decimal place.
Answer:
56.29
Step-by-step explanation:
56.29^° is the answer
The bearing of town C from town A at the given position of the three towns is determined as 93.3⁰.
Distance of C from A
The distance of town C from town A is calculated by applying Cosine rule. The distance of town C from town A is represented by small letter "b" as shown in the image.
b² = a² + c² - 2ac[cos B]
b² = (8)² + (7)² - 2(8 x 7 x cos77)
b² = 87.81
b = √87.81
b = 9.37 km
Angle AThe value of angle A is determined by applying Sine rule as shown below;
sin A/a = sin B/b
sin A = (a x sin B)/b
sin A = (8 x sin 77)/9.37
sin A = 0.832
A = sin ⁻¹ (0.832)
A = 56.3⁰
Bearing of town C from town AThe bearing of town C from town A is determined from the sum of 37⁰ and angle A.
θ = A + 37⁰
θ = 56.3⁰ + 37⁰
θ = 93.3⁰
Thus, the bearing of town C from town A at the given position of the three towns is determined as 93.3⁰.
