x^2 = 15^2 + 36^2

X^2 = 225 + 1296

X^2 = 1521

x = sqrt(1521)

x =39

This is a right triangle, so we can use the Pythagorean Theorem to find x; the Pythagorean Theorem is a^2 + b^2 = c^2, where c is the hypotenuse. In this case, x is the hypotenuse. Let's set up an equation:

15^2 + 36^2 = c^2
225 + 1296 = c^2
1521 = c^2
39 = c

Answer:
x = 39

In the diagram below, BD is parallel to XY. What is the value of x?
MAXImum [283]

If two lines are crossed by another line that is called the transversal, the corresponding angles those in matching corners. In this problem, we have two parallel lines:


\overleftrightarrow{XY} \\ \\ \overleftrightarrow{BD}


In this way, x° and 76° are corresponding, therefore:

(x)° = 76°

∴ x = 76
