Answer:
Step-by-step explanation:
Comparing the triangles in the given questions, the following can be deduced:
5. The scale factor =
=
≠ 
So that;
QR is similar to UT, PR is similar to US, but PQ is NOT similar to TS.
Thus, the triangles are NOT similar.
6. Scale factor =
=
= 
= 1.5
So that;
QR is similar to UT, PR is similar to US, but PQ is similar to TS.
Thus, the triangles are similar by Side-Side-Side (SSS).
7. Here, an exact scale factor can not be determined. Thus, the triangles are NOT similar.

b (4b+19)
Answer:
270cm squared
area of shaded part rectangle is 180
are of triangle is 48 and 42 respectively you add the three to get 270
Account 1 : y = 2500(1.078)x
account 2 : y = 2500 + 300x
after the second year a1 exceeds a2
after 2 years, a1 = 5390
after 2 years , a2 = 3100
< = angles
<a = 145
<b = 35
<c = 145
<d = 145
<e = 35
<g = 35
<f = 145
hope this helps
