A triangle has sides of lengths 12, 14, and 19. Is it a right triangle? Explain.

1 answer:

7 0

A^2 + b^2 = c^2
C should equal to the longer side, which would be 19. 
Plug in other two numbers for A and B. 
12^2 + 14^2 = 19^2 
Now see if it's correct. If it is, then it's a right triangle, if it's not then it isn't a right triangle. 
144 + 196 = 361 
340 = 361 
It's not a right triangle.

What is the equation of the line that passes through the point (5, 4) and has a slope of 6/5?

leva [86]

Answer:

y = 6/5x - 2

Step-by-step explanation:

y = mx + b

plug in values

4 = (6/5)(5) + b

simplify

4 = 6 + b

subtract 6 from both sides

-2 = b

y = 6/5x - 2
