Answer:
-1/2
Step-by-step explanation:
-2 (4 - x) = 12x – 3
-8+2x=12x-3
+8 +8
2x=12x+5
-12x -12x
-10x=5
/-10 /-10
= -1/2
Well you can start by drawing a triangle with the information
the size of angle B can be found using the Law of Sine

the size of angle C can be found using angle sum of a triangle.
The length of side c can be found using the Law of Cosines

hope it helps
Answer:
235
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9*12.5=112.5
rec 2: (13.5-5.5)*(19.5-9-7)=28
rec 3:7*13.5=94.5
Then:
112.5+28+94.5=235
