Angle OAB is a right angle, since line AB is tangent to the circle at A. Thus, triangle AOB is a right triangle.
Applying the Pythagorean Theorem: 5^2 + 12^2 = |OB|^2
Then |OB|^2 = 13^2, and |OB| = 13.
We find x by subtracting |OC| from 13: 13 - 5 = 8.
Line segment has length 8; x = 8.
Answer: She should sell each T-Shirt for at least $4.41
Step-by-step explanation:
First you need to figure out what the total cost of the 200 t shirts was plus shipping. so 200 t shirts for 2.8 would cost $560 + a 5% shipping fee ($28) = 588 if she wants to markup by 150. you would then multiply 588 * 1.5 = $882. This would be the final money she wants to make by the end of her school carnival. Divide 882/200 (amnt of t-shirts) to get $4.41 per shirt
Answer:
This is a picture of You
Step-by-step explanation:
Answer:
The angle is 50 degrees.
Step-by-step explanation:
You'll see, the angle that is on the left of the 70° angle has to be 110°, because a straight line has 180°.
Now, the inner angles of a triangle have to sum 180°. So if the lower angle is 110° (because you just calculated it), and the upper angle is 20°, the third angle is:
180° = 110° + 20° + x
180° = 130° + x
180° - 130° = x
50° = x
Now this third angle is on the bottom left part of the triagle, and it's 50°. It also opposite to the angle 1, which is the one you want to calculate. Because they are opposites, they are identical, meaning that they both are 50°. This is due to a geometrical rule.
4x²-36x/x-9=4x(x-9)/x-9=4x
4x=0
f(0)=0
