n>-5

Step-by-step explanation:

We have to distribute the -7 first, so:

-105<-7(5-2n) becomes:

-105<-35+14n

To find n, we have to add 35, so:

-105<-35+14n

+35   +35

We get 14n>-70. Now, we have to divide each side by 14 to find n.

14n/14>-70/14.

So, the solution becomes n>-5.

18°

Step-by-step explanation:

We see that ∠3 is 90, and ∠QPS and ∠3 are supplementary so ∠QRS is also 90°. ∠QRS = ∠1+∠2 so we have that:

∠1 + ∠2 = 90°

Then we plug in the known values for angles 1 and 2:

7x-19+x+5=90

When you solve for x you get:

x = 13

Then plug x back into the equation of ∠2 to get:

13+5=∠2

Therefore, ∠2 is 18°
