Answer: 1.567 × 10⁹
Step-by-step explanation:
1.6 × 10⁹ = 1.6 × 1000000000 = 1,600,000,000
3.3 × 10⁷ = 3.3 × 10000000 = 33,000,000
1,600,000,000 - 33,000,000 = 1,567,000,000
10⁹ = 1,000,000,000
1.567 × 1,000,000,000 = 1,567,000,000

If the sum of measures of angle a and b is 280 degrees, what is the measure of angle C?
A. 80 degrees
B. 160 degrees
C. 140 degrees
D. 40 degrees
Answer:
40 degrees
Step-by-step explanation:
because angle b and angle a are vertical angles they are congruent and if they add up to 280 you just have to divide that by 2 to get the value of one of the angles
280/2=140
because angle c and angle b are supplementary they are going to add up to equal 180
180-140=40 so c=40
Answer:
40

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.
