Kevin drew a triangle with angle measures of 30 degrees and 40 degrees and side measures of 5cm,7cm, and 8cm. Explain, using sides and angles, which type of triangle Kevin drew?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

a
