Parallel Lines m and n are cut by a transversal, t, as shown. If m∠3 is 60°, what is the m∠5? Select one:

60° because ∠3 and ∠5 are alternate exterior angles

60° because ∠3 and ∠5 are supplementary angles

60° because ∠3 and ∠5 are corresponding angles

60° because ∠3 and ∠5 are alternate interior angles

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

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
