QR is the radius of R and PQ is the tangent to R. Find the value of x.

Mathematics
1 answer:

5 0

Answer:

x = 39

Step-by-step explanation:

We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:

80^2 + x^2 = 89^2

6400 +x^2 = 7921

x^2 = 1521

x = \sqrt{1521}

x = 39

nadya68 [22]

Answer:

True.

Step-by-step explanation:

The distributive property of real numbers says

a(b + c) = ab + ac. Here, the number outside multiplies the numbers only in the parentheses. Therefore the statement is true. The number located outside can be applied to only numbers in parentheses.
