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