In the diagram shown at left, three lines intersect to form a triangle.<br> What is the value of x?

Phoenix [80]

Answer:

39°

Step-by-step explanation:

For a straight line, the sum of angle is 180°

At the point where we have the 107°, the inner angle in the triangle will be 180-107=73°

68° is alternate angle to the inner angle in the triangle

Since the sum of angles in a triangle are 180°, then angle x will be

X=180-73-68=39°

Therefore, missing angle is 39°

Answer:

8x + 3y = -47

Step-by-step explanation:

1. Use the y = mx + b form to find b:

$y=-\frac{3}{8} x+b\\-4=\frac{3}{8}(5)+b\\-32=15+8b\\-47=8b\\-\frac{47}{8} =b$

2. Plug in b for the new equation:

$y=-\frac{3}{8} x-\frac{47}{8}$

3. Get rid of the denominators and simplify everything into standard form

(ax + by = c)

$y=-\frac{3}{8} x-\frac{47}{8}\\8y=-3x-47\\3x+8y=-47$
