C - 7.6 = -4
c = -4 + 7.6
c = 3.6
Answer:
A. 20.5
Step-by-step explanation:
We can use the Pythagorean theorem to solve this equation for the missing side length, X.
a^2 + b^2 = c^2
We have a and b, we just need c, the hypotenuse.
14^2 + 15^2 = c^2
196 + 225 = c^2
421 = c^2
Now, we will square both sides:
The answer is about 20.5

D. comes first as it has the most significant figures. Hope this helps!!
18.5-0.5= 18
18/3= 6
So r=6
