Answer:
They must be 90 degree angles
Step-by-step explanation:
A fraction could be 8/50 because you just multipley both of the numbers
x - 7y = 19 <em>multiply both sides by 5</em>
5x - 35y = 95
Substitute 5x = -2y - 16:
(-2y - 16) - 35y = 95
(-2y - 35y) - 16 = 95 <em>add 16 to both sides</em>
-37y = 111 <em>divide both sides by (-37)</em>
y = -3
Put the volue of y to the first equation:
x - 7(-3) = 19
x + 21 = 19 <em>subtract 21 from both sides</em>
x = -2
<h3>Answer: x = -2 and y = -3 → (-2, -3)</h3>
Answer:
move down five and move right ten
Answer:

Step-by-step explanation:
we know that
In a right triangle
Applying the Pythagorean Theorem

where
c is the hypotenuse (the greater side)
a and b are the legs (perpendicular sides)
In this problem we have

substitute
