Does a triangle have to have a 90 degree angle?
Unless it is a religious triangle it does not have to have any angels! Seriously, though, a triangle does not have to have a 90 degree angle. In terms of its angles, the only requirement is that the measures of the three angles adds to 180 degrees (or pi radians).
What is the measure if an arc that has 148 degrees tangent chord angle?
16*pi*r/45 where r is the radius.
How do you find the degree measure of a central angle in a circle if both the radius and the length of the intercepted arc are known?
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
What is area to the nearest tenth of a 120 degree sector of a circle with radius of 8 ft?
Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.
Relationship between degree of measure of a central angle and the arc it intercepts?
Arc length is equal to radius times the angle the arc subtends (makes) at the centre of the circle, but the angle needs to be in radians. Set your calculator to radians instead of degrees, or, to change degrees to radians, divide by 180 and times pi. The formula comes from the fact that the length of the arc is proportional to the circumference of the circle in the same ratio as the angle at the centre is to the complete revolution at the centre, so length of arc: circumference of circle = angle size : 360o arc/(2*pi*r) = angle in degrees/360 or angle in radians/(2*pi) so arc length is angle in degrees divided by 360, times the circumference of the circle. Answer will be in the same measurement unit as the radius.
What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
What is 141.37 in terms of pi?
To express 141.37 in terms of pi, we would divide 141.37 by pi (approximately 3.14159). This gives us approximately 44.98, meaning that 141.37 is roughly 44.98 times pi. In mathematical terms, 141.37 ≈ 44.98π.
What is an angle that completes a 30 degree angle?
pi/6 radians.
What is the measure of a angle with 45 degrees?
It is pi/4 radians.
Does a triangle have to have a 90 degree angle?
Unless it is a religious triangle it does not have to have any angels! Seriously, though, a triangle does not have to have a 90 degree angle. In terms of its angles, the only requirement is that the measures of the three angles adds to 180 degrees (or pi radians).
What is the measure of a 71 degree angle?
pi*71/180 radians
What is 45 degrees angle?
45 degrees is the angle halfway between the floor and the wall of your house.
What kind of angle is 4 pi divided by 5?
pi = 180 degrees pi / 2 = 90 degrees 2 pi = 360 degrees so pi / 5 = 180 / 5 = 36 36 x 4 = 144 degrees a 144 degree angle is obtuse
Can we take theta in terms of degree?
Pi radians is 180 degrees. So if you have theta in radians, multiply by 180/Pi
How to rewrite angle in degree measure to radian?
180 deg = pi radians So x deg = x*pi/180 radians
How do you find the length of an arc and leave you answer in terms of pi?
The length of an arc is the radius times the angle in radians that the arc subtends length = radius times angle in degrees times pi/180
What is the measure if an arc that has 148 degrees tangent chord angle?
16*pi*r/45 where r is the radius.
