Find the value of x. m∠TUV = 172° m∠TUL = (x + 16)° m∠LUV = (11x)° A) 7 Eliminate B) 10 C) 13 D) 16

C.) 13

Step-by-step explanation:

x + 16 + 11x = 172

16 + 12x = 172

12x = 156

156/12

x = 13

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

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
