Question

Triangle 1 is a scale drawing of Triangle 2 as shown below. Based on the information shown in these triangles, what is the length of the side x? A. 9 B. 15.75 c. 7

Answer 1

Answer:

x = 7

Explanations:

Since triangle 1 is a scale drawing of triangle 2, the ratio of corresponding sides will be the same.

Therefore:

$\frac{4}{6}=\text{ }\frac{x}{10.5}$

Cross multiply:

4(10.5) = 6x

42 = 6x

6x = 42

x = 42/6

x = 7
