A triangle is 180°; therefore:
x = 180-52-43
x = 85
x° = 85°
The first one. The second looks like (p-6)+2. The third looks like (2-p)6. And the fourth looks like 6+ (2+p)
Slope = rise/run = (change in y)/(change in x)
Slope = (4-6)/(0-(-4)) = (-2)/(4)
Slope = -1/2 = -0.5
F(x)=4+6+5/4+1
F(x)=4+6+5/5
F(x)=10+1=11
Answer =11
