This question was already solved but I forgot how to write the similarity statement

what I know already:

scale factor is 30.1/3.6

building is 15.891(inf decimal) metres

but the question asks to round to the nearest metre so
The building is 16 metres tall

just need help with the similarity statement

it says "the same time of day"

use that fact

it either has to be AA~, SAS~ or SSS~

so triangle: ABC ~ triangle: DEF (AA~)

so if I'm correct the next step would be "AB/BC=DE/EF" then plug in the numbers

"AB/30.1 = 1.9/3.6

3.6x=57.19

x=57.19/3.6

x= 15.8861(inf decimal), same answer as 1.9*(30.1/3.6)

#

also I think I could maybe solve the missing angles, using elimination

because both of these triangles can be written as

1A+90+1C=180

swift girder

so yes I could find out the values of the other angles
