Answer:
x°=113°
y°=67°
z°=49°
Explanation:
Looking at the right triangle exclusively, we know that it must have 180° in total.
Set up an equation that represents this:
28°+39°+x°=180°
Simplify:
67°+x°=180°
Solve:
x°=113°
Now, we also know that x°+y°=180°, because they form a line. Now that we know the value of x°, plug it in to this equation:
113°+y°=180
Solve:
y°=67°
Finally, apply the same logic with the first triangle with the other triangle:
64°+67°+z°=180°
Simplify:
131°+z°=180°
Solve:
z°=49°
