Expert Solution
Step 1

Given: Andrew has written lengths and angles of two right-angled triangles. 

As both the triangles are right-angled triangles, so firstly check for the length of hypotenuse using the Pythagoras theorem.

 

The Pythagoras theorem states that in a right-angled triangle, the sum of square of the length of mutually perpendicular sides is equal to the square of the third side.

a2+b2=c2  

Step 2

Check for triangle 1.

The length of the two sides is 130 ft each.

Using Pythagoras theorem, solve for the hypotenuse of the triangle 1.

1302+1302=16900+169001302+1302=338001302+1302=183.84782

Therefore, it can be concluded that the hypotenuse of the first triangle is written correctly.
