Plz help me The photograph is enlarged to make a poster. The photograph is 10cm wide and 16cm high.

a, The poster is 25cm wide. How high is the poster?

b,. The building on the poster is 30cm tall. Is it possible to figure out how tall the building is on the photograph? If you think it is possible, show how. If you think it is not, explain why.

A.40

B.yes and it is 12

Step-by-step explanation:

A. the rule is 2n+(1/2n) so

2x16+(1/2of16)

32+8

40

B.yes it is possible, follow the rule for a 2n+(1/2n)

2x12+(1/2of12)

24+6

30 so the answer is yes, it is possible, and its 12

A: 40 cm

B:  48

It is possible since we know how tall the photograph is. Using the ratio, the height of the poster can be found. (let x be the height)

16 / 10 = x / 30

x = 48

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
