Answer:
Step-by-step explanation:
Pythagorean Theorem:
where a and b = legs and c = hypotenuse
we are given a leg and the hypotenuse so we plug in what we have into the formula
now we solve for b
step 1 subtract 20^2 from each side
finally we want to get rid of the exponent on the b
to do so we take the square root of each side
we're left with b = 21
Note: They Pythagorean theorem only works with right triangles
Answer:
x = 0.16
Step-by-step explanation:
Step 3:
Solve the equation for x by finding a , b , and c of the quadratic then applying the quadratic formula.
Then, evaluate for x:
x = 0.16259190... which is about,
x = 0.16
