Answer:
Step-by-step explanation:
Given that, O is the center of the circle and PQ is a tangent to the circle at point Q. OQ is a radius of the circle.
We know that, a tangent to a circle is a line which just touches the circle. And the angle between the tangent and radius is 90°.
Hence, ΔOQP is a right angle triangle. We know that the sum of the measurements of all the 3 angles of a triangle leads to 180°. So,
7^5

Answer:
Step-by-step explanation:
Secant and tangent theorem: Square of measure of tangent is equal to the product of length of whole secant and length of exterior secant segment, i.e.
.
The whole secant with exterior secant 5 in is 5+y in. Using this theorem you can state that
.
Solve this equation:
in.
Answer: y=11.2 in.
The total cost, in pounds, for X jumpers at £15 each and Y shirts at £12 each can be written as the mathematical expression: 15X + 12Y, where X and Y are the quantities of jumpers and shirts respectively.
To write an expression for the total cost of X jumpers at £15 each and Y shirts at £12 each in pounds, you need to multiply the cost per item by the quantity of each items and then add these two products together.
So, the total cost can be given as:
where
In this expression, '15X' stands for the total cost of the jumpers and '12Y' stands for the total cost of the shirts.
