Answer:
x = 38
∠P = 26º
Step-by-step explanation:
The sum of the angle in a triangle is 180
x + (x + 78) + (x - 12) = 180
Combine like terms
3x + 66 = 180
Subtract 66 from both sides
3x = 114
Divide both sides by 3
x = 38
-----------------------
∠P = x - 12
∠P = 38 - 12
∠P = 26º
 
        
                    
             
        
        
        
Answer:

You first have to multiply the -5.3 times the -1.9. Once you do that, you get 10.07. Then, you add the -7.5.
Here are the equation steps:
(-7.5) + (-5.3)x(-1.9)
(-7.5) + (10.07)
2.57
