The value of the radius of T is 28 units

<h3>How to determine the value of the radius of T</h3>

From the question, we understand that:

Segment AB is tangent to T at B

This means that

<ABT = 90

So, we have a right triangle

Let the radius of the triangle be r

By the Pythagoras theorem, we have

AT^2 = AB^2 + VT^2

This gives

(25 + r)^2 = 45^2 + r^2

Open the bracket

625 + 50r + r^2 = 2025 + r^2

Subtract r^2 from both sides of the equation

625 + 50r = 2025

Subtract 625 from both sides of the equation

50r = 1400

Divide both sides by 50

r = 28

Hence, the value of the radius of T is 28 units

18.725 = 18725/1000 = 3745/200 = 749/40 = 18 29/40

so, your answer is 18 29/40

Answer:

∠y = 62.5°

∠x = 27.5°

Step-by-step explanation:

z is right angle. ∠z = 90°

∠x = ∠y - 35

∠x + ∠y + ∠z = 180 {Angle sum property of triangle}

y - 35 + y + 90 = 180

y + y - 35 + 90 = 180 {Combine like terms}

2y + 55 = 180

2y = 180 -55 {Subtract 55 from both sides}

2y = 125 {Divide both sides by 2}

y = 125 /2

∠y = 62.5°

∠x = 62.5 - 35 = 27.5°
