From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm find the radius of the circle.

Here, O is the center of the circle.
<u>⟼</u><u> </u><u>Given</u><u> </u><u>:</u>
<u>⟼</u><u> </u><u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u> </u> We have to find the radius OP.
Since QP is tangent, OP perpendicular to QP.
(Since, Tangent is Perpendicular to Radius ⠀⠀⠀⠀⠀⠀⠀at the point of contact)
So, ∠OPQ=90°
<u>⟼</u><u> </u><u>By</u><u> </u><u>Applying</u><u> </u><u>Pythagoras</u><u> </u><u>Theorem</u><u> </u><u>:</u>
OP² + RQ² = OQ²
OP² + (24)² = (25)²
OP² = 625 - 576
OP² = 49
OP = √49
<u>OP</u><u> </u><u>=</u><u> </u><u>7</u><u> </u><u>cm</u>
<u>Hence</u><u>,</u><u> </u><u>The</u><u> </u><u>Radius</u><u> </u><u>is</u><u> </u><u>7</u><u> </u><u>cm</u>

Answer:
B) sin55/8 = sin30/b
Step-by-step explanation:
AP3X :)
The first step is to simplify the absolute value. 0.8 - 3/5 is equal to 0.8 - 0.6 which is 0.2. Now we do order of operations. Since the absolute value of 0.2 is 0.2, we can now do PEMDAS and solve. First is multiplication. 0.2 * 10 is 2. Now we have to do 5 - 3 which gives us our answer of 3, or C.
Answer:
40
Step-by-step explanation:
To find the answer, we will have to find the percentage of $273 to $ 3500, and we can use the formula:

In this case:
273/3500 x 100%
=39/500 x 100%
=7.8%
Therefore the annual interest rate would be 7.8%.
Hope it helps!
