The measure of the vertex angle of an isosceles triangle is four times the measure of a base triangle. find the degree measure of the vertex angle

24/56=hx^7

step-by-step explanation:

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

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

hope this is what you were asking for!
