Answer:

Step-by-step explanation:

Pythagorean Theorem

c^2 = a^2 + b^2

a = 20

b = 15

c = ?

c^2 = 20^2 + 15^2

c^2 = 400 + 225

c^2 = 625 Take the square root of both sides.

√c^2 = √625

c = 25

The third side is 25 cm long.

What is the length of ST? Please explain your answer

Aliun [14]

We know that

If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment. (Intersecting Secant-Tangent Theorem)

ST²=RT*QT

RT=7 in

QT=23+7-----> 30 in

ST²=7*30-----> 210

ST=√210-----> 14.49 in

the answer is

RT=14.49 in
