The correct answer is - b. African.
The African tectonic plate will move the most of all tectonic plates. It is moving into a northeastern direction, and it is pushing towards the western part of the Eurasian tectonic plate and it is squeezing the Arabian tectonic plate between itself and the Eurasian tectonic plate. Because of this movement, the African tectonic plate in a relatively small amount of time (geologically speaking) will merge with Europe, and since both of the plates are of same density a large mountain range will start to form because of the pressure between the two plates. Also, the Mediterranean Sea will be cut of from the Atlantic Ocean and it will dry out.
Answer:
An alpha star is the brightest star in the constellation.
Explanation:
The first option is not correct because this type of star is not identified as such because of its location in the constellation.
The second option, as the first one, is not correct because the location of this type of star has nothing to do with its identification as such.
The third option is not correct because the distance from Earth is not taken into account when a star like this is identified.
The fourth option is correct because an alpha star is a star that is brightest in the constellation, and it can be located anywhere in it, and it can be of any color a star can be.
The fifth option is not correct because the color of the star can be of any type, but what matters the most is how bright it is compared to the other stars in the constellation.
Answer:
x = 15
Explanation:
As we can see it is an isosceles triangle so
The perpendicular line joining the vertex and base of isosceles triangle bisects the base. so
Taking the triangle of right side
hypotenuse (h) = 25 inches
base (b) = 20 inches
perpendicular (p) = x = ?
We know by using Pythagoras theorem
p= √h² - b²
x = √ 25² - 20²
= √ 225
x =15
Hope it will help :)
