First covert 39.5% to a decimal to get 0.395.
0.395 written as a fraction is

Simplify

to get
I believe it is 72 because there is a right angle so thats 90 the known angle is 18 so thats 18-90-18=72
Answer: approximately 10.4 feet
Step-by-step explanation:
Answer:
The slope-intercept form, or y=mx+b, would be y=4x-16.
Step-by-step explanation:
if you use the data given, it would be 4=4(-5)+b.
4=-20+b
Then you would subtract '-20' from both sides.
-16=b.
Now, if you plug in the numbers without the (x,y). It would be,
y=4x-16.
Since the legs are the same length, we know that the remaining two angles must be the same.
120+2x=180
2x=60
x=30
Final answer: x=30 degrees
