d. Geoid models have improved through time.

e. NGVD29 was matched to more tidal stations than NAVD88

Explanation:

a. Datums can be established leveling with trigonometric form, is a method to determinate different elevations.

d. Geoid models have been improved through time in the gravimetric geoid model and increase accuracy, actually, these models keep refining, there were errors ins this models, nowadays are more accurate.

e. NGVD29 was matched by tidal stations more than NAVD88.

NGVD29 was established by 26 tidal gauges in United Stated and Canada, maps were prepared, but NGVD29 was replaced because is less accurate than NAVD88.

NAVD88 were not used Additional tidal.

False sentence

b. The average sea level doesn't correspond to our current vertical data, this depends on our location.

For example

Rinconada in Peru is the highest human establishment in the world to 5100 m.

Everest is the highest summit in the world to 8848 m.

This marker indicating the sea level is located in Jerusalem.

c. Often is used levels, but there are other methods like set-up, bench mark.

f. the Dynamic heights are not the same as orthometric heights, because the dynamic heights are perfect, but the orthometric heights can change slightly, in a few words are imperfect heights.

bixtya [17]

Answer:

#include<iostream>

using namespace std;

int main(){

//initialize

int a, b,c;

//print the message

cout<<"Enter the three sides of the triangle: "<<endl;

//store in the variables

cin>>a>>b>>c;

//if-else statement for checking the conditions

if(a == b && b == c && a == c){

cout<<"\nThe triangle is equilateral";

}else if(a != b && b != c && a != c ){

cout<<"\nThe triangle is scalene";

}else{

cout<<"\nThe triangle is isosceles";

}

return 0;

}

Explanation:

Create the main function and declare the three variables for the length of the sides of the triangle.

print the message on the screen for the user. Then the user enters the values and its store in the variables a, b, and c.

use the if-else statement for checking the conditions.

Equilateral triangle: all sides of the triangle are equal.

if condition true, print the equilateral triangle.

Scalene triangle: all sides of the triangle are not equal.

if condition true, print the Scalene triangle.

if both conditions is not true, then, the program moves to else part and print isosceles.

Strike441 [17]

n where n is the number of chances user takes to enter a blank number and n>=1.

<u>Explanation:</u>

The loop starts with a universal condition where it is initialized using a true value. Hence the iteration count goes to 1. The user is asked to enter a number after 1st iteration. If number is a blank number, the loop is terminated, else the loop goes on until the users enters a blank number. Hence the iterations depend on the number of chances taken by the user to enter a blank number. Since the user is going to enter a number at least once, the minimum value of n will be 1.
