We have used the angle sum property of any general triangle which states that the sum of all three angles of any triangle must be 180 degrees. Answer and Explanation: The Sum of all angles of a triangle must be 180 degrees. Now in an equilateral triangle, all the angles...
According to Hooke’s law: τ = Gϕ, the change of angle ϕ also becomes zero in the centre line of the plate elements. Thus, it is obtained from Eq. (5.14) that (5.33)ϕ=θrs+∂ux∂s=0 The variation of the warping ux can then be found to be (5.34)ux=−θ∫rsds=...
For example, the sum of the interior angles of a triangle drawn on a plane is 180 degrees. If we make the same construction on the sphere using its geodesics, great circles, we find that the “deficit angle,” the difference of the sum of the interior angles and 180 degrees, is ...
In an isosceles right triangle, one of the angles is a right angle, which means that it measures 90 degrees.Answer and Explanation: The measure of a base angle of an isosceles right triangle is 45 degrees. In any triangle, the sum of all three angles equals 180 degre...
Nematodynamics formulates that the director tilt angle ϕ(x, t) at time t and distance x from a surface obeys the dynamic equation γ1∂ϕ∂t=K∂2ϕ∂x239. With a periodic distortion ϕ(x=0,t)=ϕ0sin(ωt) imposed at x = 0, the time-dependent solution ...

We measure the noise of the cavity output field at optical quadrature angles ranging from −33° to 33° (Fig.3c), where the 0° quadrature is defined as the one with no mechanical displacement information. Depending on the quadrature angle, we observed optical squeezing (up to 50 kHz ...
Given that line segment 𝐴𝐵 is a diameter in circle 𝑀 and the measure of angle 𝐵𝑀𝐷 equals 59 degrees, find the measure of angle 𝐴𝐶𝐷 in degrees. Let’s put what we know into the diagram. Angle 𝐵𝑀𝐷 measures 59 degrees, and we’re trying to find the meas...
If ray R2 is reflected at B, then the diagram shows that R2 travels the same distance as R1 plus an added distance 2BC. Because AB in the small triangle ABC is perpendicular to the atomic plane, and AC is perpendicular to the incident ray, the angle CAB equals θ;, the angle of ...
The hour angle is the number of degrees that the earth must rotate before the sun will be directly over your local meridian. Considering the earth to rotate 360° in 24 h, the hour angle can be described as follows: (7)ω=15°hourSTinhoursbeforesolarnoon The solar time is different from...
