Answer to Problem 3STP

The area of the triangle is option (D) 171.9 in2 .

Explanation of Solution

Given information:

The figure of a triangle with dimensions is given as follows:

  Geometry, Student Edition, Chapter 11, Problem 3STP

Figure (1)

Formula used:

(i) Pythagorean theorem for right angled triangle:

  Hypontenuse2=Adjacent2+opposite2 .

(ii) The tangent formula for a right angled triangle:

  tanθ=Opposite sideAdjacent side

(iii) Area of the triangle is A=12bh ; where b is the base and h is the height.

Calculation:

Use the Pythagoras theorem to compute the value of y.

  172=y2+132289=y2+169y=289169=10.954

Calculate the value of x using the tangent formula as follows:

  tan40°=13xx=13tan40°=130.839115.493

The area of the required triangle is computed as follows:

  A=12(10.954+15.493)(13)=12(26.447)(13)=12(343.811)=171.9055

Round off the area value to the nearest tenth, then area=171.9 in2 .

Therefore, the area of the triangle is 171.9 in2 .
