While solving a triangle, the law of sines gives a value for angle β of 68.24°. If β is an obtuse angle, what is its actual value?

step-by-step explanation:

answer: i don't understand it

step-by-step explanation: sorry

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

what's the question?

step-by-step explanation:

there is no question.
