the shadow if a metre stick is 1.3m long when a students shadow is 2.0m long. How tall is the student?
1/1.2 = x/2.0
Cross multiply and solve for x.
Where are you getting 1.2 from?!?!
To find out how tall the student is, we can use the concept of similar triangles.
In this case, we have a triangle formed by the student, the student's shadow, and the meter stick. Let's label the height of the student as 'h' and the length of the student's shadow as 's'.
We are given that the shadow of the meter stick is 1.3m, and the shadow of the student is 2.0m. Let's label the length of the meter stick's shadow as 'm'.
Using the property of similar triangles, we can set up the following proportion:
h / s = m / 1.3
Considering that the length of the student's shadow is 2.0m, we can rewrite the equation as follows:
h / 2.0 = m / 1.3
To find 'h', we need to know the value of 'm'. Since the question does not provide the length of the meter stick, we cannot determine the exact height of the student without this information.
However, if we have the length of the meter stick, we can substitute it into the equation and find 'h' by solving the proportion.
