Answer:
142125
Step-by-step explanation:
Since we given two brackets to solve we will have to take the step by step procedure
So let's solve the question
(2+377)(2-377)
Let's start with the first bracket
(2+377)
It will give us 379
So let's solve the second bracket
(2-377)
It will give us -375
So back to the question
(379)(-375)
142125
So the final answer is 142125

Answer:
r = 12
Step-by-step explanation:
From the figure attached,
QP is a tangent to the circle O at the point P.
Therefore, by the property of tangency,
OP ⊥ QP
By applying Pythagoras theorem In right triangle QPO,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
(OQ)² = (OP)² + (PQ)²
(25 + r)² = (35)² + r²
625 + r² + 50r = 1225 + r²
50r = 1225 - 625
50r = 600
r = 12
Therefore, r = 12 units is the answer.
