Answer:
b=21
Step-by-step explanation:
a^2 + b^2 = c^2
20^2 +b^2 = 29^2
b^2+400=841
b^2=441
b=21 or b= - 21
Since we are using the values for a triangle we take the positive value.
21
Use Pythagorean Theorem
If you are looking for leg given the other sides of the right triangle: just do bigger square minus small square
and take square root
so 29^2 - 20^2
And then sqrt it!
sqrt(29^2-20^2)
7
Each step in the change happens when the original number is subtracted by four. 27 minus four equals 23 and so on.
x = 13
Corresponding angles equal one another.
