Answer:



Step-by-step explanation:
we current vertices of the given triangle
remember that,

so we obtain:



Answer: B
Step-by-step explanation:
(-3, -1) and (4, 5) are the points given
Slope formula: 


Answer:
yes they are not equal because (x + a) = 2x + 2a
Explanation:
To find x we need to find the unknown side that connects the two triangles using the Pythagorean theorem:
a² + b² = c² (c is always hypotenuse)
So:
a² + 6² = 9²
a² = 9² - 6²
a² = 81 - 36
a² = 45
a = sqrt45
Now we do the same thing for the other triangle:
x² + 5² = sqrt45²
x² + 25 = 45
x² = 20
x = 2√5 or 4.5...
