Surveyors measure two points on the ground and from each point they measure the angle between them and the top of the mountain to give them a triangle.

测量员在地上测量两个点，并从每个点测量它们与山顶之间，从而得到一个三形。

If you were to measure this angle right over here, you would get theta.

这里已知斜同水平是θ 未来视频中 我们会明确这个为30度 45度等等。

The farther away an object is, the angles between the light rays entering our eyes are smaller, and our lens doesn't need to bend them as much, so tiny muscles relax and flatten it.

物体离我们越远，照进眼睛光线之间越小，晶状体不需要弯曲那么多，因此微小肌肉放松，拉平水晶体。

The Earth spins on an axis that's tilted 23.5 degrees from vertical.

地球绕着地轴自转，地轴与轨道平线为 23.5 度。

Harry watched lazily as Professor Trelawney began to point out the fascinating angle Mars was making to Neptune.

哈利懒洋洋地看着，特里劳妮教授开始讲解火星与海王星形成奇妙。

Since we just saw that this change vector has a constant magnitude, the only way for this dot product to stay the same is if the angle it makes with that collision line stays the same.

由我们刚刚看到这个变化向量大小是恒定，点积保持不变唯一方法就是它与碰撞线形成保持不变。

Using the same basic principles, we can see that the difference between the shadow angles is the angle between our positions 35 degrees, or just about a 10th of the way around the globe.

利用相同基本原理， 我们可以看出， 影子度差异即是我们位置间，为35度，大约相当地球周长十分之一。

The repulsion between the unbonded pairs is even stronger than repulsion between the shared pairs, so the two hydrogens get pushed a little further to an angle of 104.5 degrees.

未成键电子对之间斥力甚至强共享电子对之间斥力，因此两个氢原子被稍微推得更远， 形成104.5度。

The flux, you’ll recall, is equal to the magnetic field times the area, times the cosine of the angle between the magnetic field and a line perpendicular to the loop.

磁通量等磁场乘以积，再乘以磁场与回路线之间余弦值。

The angle for the side of the Gaussian cylindrical surface is between a  horizontal electric field and the direction of any dA on the side which is always 90 degrees.

高斯圆柱侧是在水平电场和侧上任意dA方向之间度，这个度始终是90度。

Now, while Earth's axis is currently around 23.5 degrees off vertical, over the last million years, it has varied between 22.1 and 24.5 degrees.

目前， 地球自转轴与方向约为23.5度，但在过去一百万年间， 这一度在22.1度到24.5度之间波动。

We imagine automatically that there are 90 degrees between the ascendant, where the sun rises, and the midheaven, where it culminates, roughly around noon.

我们通常会自然而然地认为，上升点（太阳升起方位）与天顶（太阳大致在正午时分达到最高点位置）之间存在90度。

But the farther away from the equator you go towards the poles, the sun's angle to the horizon gets shallower and shallower.

但是， 当你从赤道向两极移动时，太阳与地平线会变得越来越小。

He had certain rules like, you know, you can only have 45 degree angles or 90 degree angles to link places.

他有一些规定， 比如你知道，连接地点只能使用45度或90度。

The first is that you want the angle of your rock relative to the water to be about 20 degrees.

首先，你希望石头与水约为20度。

The angle of a light ray after it passes from one medium to another is called the angle of refraction, and it's related to the angle of incidence by Snell's Law.

光线从一种介质射入另一种介质后称为折射，根据折射定律它与入射有关。

Table 5 lists parameters such as tunnel–load spacing, included angle, and tunnel buried depth.

表 5 列出了隧道-负载间距、和隧道埋深等参数。

Well, calling the angle between the mirrors theta, the answer here is however many times you can add theta to itself before you get more than halfway around the circle, which is to say more than pi total radians.

好吧， 设两镜子之间为θ，答案就是你可以将θ加到自身次数， 到总和超过半圆，也就是超过π弧度。

F3, at an angle of, we'll call it Fi, so the angle from this horizontal line here is Fi.

F3，在一个度，我们称它为 Fi，所以这里与这条水平线是 Fi。

The path difference is equal to the width of the slit, D, times the sine of the angle between the point on the screen and a line straight from the slit to the screen.

路径差等狭缝宽度 D 乘以屏幕上点与从狭缝到屏幕线之间正弦值。
