Help! Solve for the value of x.
Ludmilka [50]

Answer:

x=6 degrees

Step-by-step explanation:

I know that 31+(10x-1)=90. Then I have to subtract 31 from 90 to get 10x -1.

That's 59. I solve for x in the equation 59=10x-1.

That is the same thing as 60=10x, which is also the same as 6=x.

jarptica [38.1K]
The Pythagorean theorem works.

12^2+9^2=c^2
144+81=c^2
225=c^2
15=c

Therefore the perimeter is 12 + 9 + 15 = 36 in. (B)
