If you can answer this, please help !

the total of angle's in traingle is 180

so 85+53+c=180

c=180-138

c=42

Step-by-step explanation:

180° = m∠A + m∠B + m∠C

180° = 85° + 53° + m∠C

180° = 138° + m∠C

m∠C = 180° - 138°

= 42°

your answer would be 10x - 1

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
