1. $2\cdot(8-3)-6=2\cdot5-6=4$

2. $14c-6=22\implies14c=28\implies c=2$

3. $2x+18=5x\implies 3x=18\implies x=6$

4. $18-c+9c+6=24+8c$

5. $8x=-56\implies x=-7$

Hope this helps :)

The measures of angles of a triangle are shown in the figure below solve for

irina1246 [14]

Answer:

x=51

Step-by-step explanation:

There are two ways you can go about this

You can either say that the sum of interior angles in a triangle is equal to 180 so you do 180-39-90=51

Or you could use the exterior angle theorem, which means that 90=39+x, simplify that and you get that x=51
