Math Problem Statement

What is the height (x) of the smaller triangle based on the given dimensions of the larger and smaller triangles?

Solution

This is a geometry problem involving a triangle. From the diagram:

  1. There is a large triangle, and within it, a smaller triangle that appears to be similar to the larger triangle.
  2. The dimensions of the larger triangle are labeled: the height is 3232, the base is 24+9=3324 + 9 = 33.
  3. The smaller triangle's height is unknown (xx), and its base is 99.

Since the two triangles are similar, their corresponding sides are proportional. Let's solve for xx:

Height of smaller triangleHeight of larger triangle=Base of smaller triangleBase of larger triangle\frac{\text{Height of smaller triangle}}{\text{Height of larger triangle}} = \frac{\text{Base of smaller triangle}}{\text{Base of larger triangle}}

Substitute the given values: x32=933\frac{x}{32} = \frac{9}{33}

Solve for xx: x=93332x = \frac{9}{33} \cdot 32

Simplify: x=93233=288338.73x = \frac{9 \cdot 32}{33} = \frac{288}{33} \approx 8.73

Thus, the height of the smaller triangle is approximately 8.738.73.
