<h3>As we know that sum of three angles of triangle is 180º.</h3>
we have


<h3>

The angles a and c are equal so,</h3>
- cb = ab. [ sides opp to equal angles are equal]
so x is also 16
<h3>

Now we have two side we can easily find the third side by P.G.T</h3>
<h3>so the r is root 512 and x is 16.</h3>
Hope it helpa
Answer:
verdade
Explicação:
A afirmação é verdadeira de que o estudo dos fundos marinhos trouxe evidências de que as cordilheiras oceânicas são regiões onde a nova crosta oceânica é formada. Essa nova crosta oceânica é formada nas cordilheiras do meio do oceano devido à erupção vulcânica no fundo do mar no processo de propagação do fundo do mar. Nas cordilheiras do meio do oceano, um novo fundo do mar é formado continuamente durante o processo de propagação do fundo do mar.
It is false that the mathematical system in Mesopotamia was based on the number 7. O.
<u>Explanation:</u>
The mathematical system is Mesopotamia was based on the number 60 at it's base and not on 7. This numeral system is known as sexagesimal which had 60 at it's base.
This originated in the 3rd millennium BC and passed on to the ancient Babylonians and it is still used for measuring angles, times, geographic co ordinates. Since the statement that the mathematical system in Mesopotamia was based on number 7 is incorrect.
The eight-digit grid coordinate gives exactness to the nearest 10 meters. Read below about the grid coordinate of the above given map.
<h3>What are the eight-digit grid coordinates for benchmark 86 (circled in red)? </h3>
Grid coordinates are said to be correctly target to a definite area, using a map that starts with upright and straight lines of same spacing and signals connected to every line to define out a destination.
The traverse vertical and horizontal lines have different figures and make little squares defined as grid squares. The more digits in the coordinate of a boundary, the improvement in precision an eight-digit provides a accuracy to the nearest 10 meters.
Therefore, the correct answer is as given above.
