the measure of an angle in standard position is given. find two positive angles and two negative angles that are coterminal with the given angle.
Answers
To find coterminal angles, you have to either add or subtract 2π. In this case, you would use 8π/4 so there is a common denominator.
Positives:
-3π/4+8π/4 = 5π/4
5π/4+8π/4 = 13π/4
Negative:
-3π/4-8π/4 = -11π/4
-11π/4-8π/4 = -19π/4
What is the measure of an angle?In geometry, an angle measure is the length of the angle formed by two rays or arms intersecting at a common vertex.
Using a protractor, angles are measured in degrees (°). Joseph Huddart created the protractor in 1801. It was a more sophisticated protractor.
The angle created at the center of a circle is measured in radians, the unit of angular measurement. It is described as an angle that subtends from a circle's center and intercepts at an arc with a radius equal to the circle's radius. 57.3° is equal to one radian.
Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle, and full rotation are the names of basic angles.

y-intercept: (0, -0.7)
x-intercept: (-1.2, 0)
Step-by-step explanation:
To find the x-intercept (x, 0) of a line substitute y by zero in the equation of the line, and from the graph, it is the point of intersection between the line and the x-axisTo find the y-intercept (0, y) of a line substitute x by zero in the equation of the line, and from the graph, it is the point of intersection between the line and the y-axisIn the given figure
∵ The line intersects the y-axis at the point (0, -0.7)
∴ The point of intersection between the line and the y-axis is (0, -0.7)
→ By using the 2nd note above
∴ The y-intercept is (0, -0.7)
∵ The line intersects the x-axis at the point (-1.2, 0)
∴ The point of intersection between the line and the x-axis is (-1.2, 0)
→ By using the 1st note above
∴ The x-intercept is (-1.2, 0)

in a circle with a radius of 7 feet, the radian measure of the central angle subtended by an arc with a length of 4 feet is 0.57 . the area of the sector formed by the arc is square feet. assume π
Answers
The area of the sector formed by the arc of the circle is 14 square feet.
What is sector of the circle?A sector of a circle is a pie-shaped section of a circle formed by the arc and its two radii. A sector is formed when a portion of the circle's circumference (as well known as an arc) and two radii cross paths at both endpoints of a arc. A sector of a circle has the shape of a pizza slice or even a pie.
Two radii and an arc encircle a portion of a circle.A circle is divided into two segments which are referred to as minor sectors as well as major sectors.The major sector is represented by the larger portion of the circle, while the minor sector is represented by the smaller portion.Now, according to the question;
Length of a sector is estimated by the formula = ∅×r
where ∅ is the angle formed by sector in radians and r is the radius of the circle.
Thus,
∅ = Length of a sector/r
The radius is r = 7 ft
The value of length of a sector = 4 ft
∅ = 4/7
∅ = 0.57 radians
Now, estimate the area of the sector.
area of a sector = (∅/2)×r²
Substituting the values.
area of a sector = (4/7/2)×7²
= (4/14)×49
area of a sector = 14 ft²
Therefore, the area of the sector is calculated as 14 ft².

Answers
Answer:
Small bag: 1kg cost 200.00p
Large bag: 1kg cost £1.90
Step-by-step explanation:
Small bag: A 200 g bag costs 40p
Medium bag: A 1 kg bag costs £1.80.
Large bag: A 2 kg bag costs £3.80.
Calculate the cost of 1 kg for the small and large bags.
Small bag: A 200 g bag costs 40p
200g cost 40p
1 gram cost 40/200
1 gram = 0.2 p
1000 g = 1kg
1kg cost = 0.2p × 1000
= 200.00p
Small bag: 1kg cost 200.00p
Large bag: A 2 kg bag costs £3.80.
Cost of 1kg = cost of 2kg bag / 2
= £3.80 / 2
= £1.90
Large bag: 1kg cost £1.90
