Which statement can be concluded using the true statements shown? If two angles in a triangle measure 90° and x degrees, then the third angle measures (90 - x) degrees.
SARE
In triangle ABC, angle A measures 90 degrees and angle B measures 50°
O Angle C must measure 50 degrees.
O Angle C must measure 40 degrees.
O Angle C must measure (90 - 40) degrees.
O Angle C must measure (90 - 30) degrees.

the probability is 0

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
