"A pair of scissors consists of two pivoted blades. In lower-quality scissors, the cutting edges are not particularly sharp; it is primarily the shearing<span> action between the two blades that cuts the material. In high-quality scissors, the blades can be both extremely sharp, and tension sprung - to increase the cutting and shearing tension only at the exact point where the blades meet. The hand movement (pushing with the thumb, pulling with the fingers) can add to this tension. An ideal example is in high-quality tailor's scissors or shears, which need to be able to perfectly cut (and not simply tear apart) delicate clothes such as chiffon and silk."</span>
If you could dig a tunnel right through the Earth you could theoretically free-fall to the centre of our planet in just eighteen minutes. You can’t, of course: such a tunnel would have to tolerate temperatures as high as the surface of the Sun and pressures three and a half million times greater than those at the Earth’s surface.
Answer:
Explanation:

Required
Find 
To do this, we make use of the following theorem
--- angle at the center and angle between two tangents add up to 180 (i.e. they are supplementary angles)
So, we have:

Answer:
plains
Explanation:
<u>It has been noted that the density of road infrastructure is higher in the plains.</u>
This is because the terrain is leveled and easier for building, which makes it more likely for cities and settlements to be built here. If the population of the region is higher, there is more need for the roads and traffic to be built.
Additionally, it is easier to drive through the plains than to through the mountains, which is why roads will be built in the plains more likely. When the terrain is leveled, <u>roads can also be built through the forests and deserts.</u>
