Answer: 
Step-by-step explanation:
Let the angle ADC = x degree
Since, By the given diagram, In triangle BDC,

⇒ 
⇒ 
⇒ 
Now, In triangle ADC,

⇒ 
⇒ 
⇒ 
⇒ 
⇒

Answer:
3/-1
Step-by-step explanation:
The slope is 3/-1 (Rise 3 on the y axis, run to the negatives by 1 on the x axis)
To find the slope of two points, use the formula of y2-y1/x2-x1 (For example, with this equation it would be 10-4/10-12)
I'm not sure what it means to interpret the slope, but hopefully this helped you!
Answer: x=55 y=145
x=55
35+90=125
125-180=55
y=145
180-35=145
I hope this is good enough:
