(1, 2)

Answer:
for number 4 the answer is 32 in (please read below)
Step-by-step explanation:
I will do one of them for now... how about number 4.
Similar triangles means we are going to setup a proportion:
Small triangle Big Triangle
Corresponding 12 15
Corresponding x 40
So the proportion is 12/x=15/40
cross multiply
12(40)=15(x)
Divide both sides by 15
giving x=12(40)/15=32
Try number 1... And I will check it for you (just post as a new question-I will be looking for it)
