Question

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).

Chapter 9.6, Problem 1E

To determine

Tofind:The length of the hypotenuse.

Expert Solution & Answer

Answer to Problem 1E

152 units

Explanation of Solution

Given information:

45∘−45∘−90∘ right angled triangle

Length of each leg =15 units

Concept Used:

In a 45∘−45∘−90∘ right angled triangle, length of both legs is equaland length of hypotenuse is given by product of length of any leg and square root of 2

In a 30∘−60∘−90∘ right angled triangle, length of longer leg is product of shorter length and square root of 3 and length of hypotenuse is given by twice the length of shorter leg.

Calculation:

Let length of hypotenuse be x

Length of hypotenuse in 45∘−45∘−90∘ product of length of any leg and square root of 2

Therefore-

x=152
