Your answer is 3
Answer I don't know the answer but i can help you find it out, so basically your going to times 3.14 by the numbers in the circle
Step-by-step explanation:
To find the length of the arc, you want to multiply the circumference of the circle by the fraction of the degrees in a full circle (360°) that the angle creating the arc PQ covers.
The angle of a complete circle is 360°. Since you are given all the angles except for the angle creating the arc PQ, you can subtract your given angles angles from 360° to get your missing angle:
360°-150°-73°-65° = 72°
The angle creating the arc PQ is 72°. That means the fraction of the full circle that the arc takes up/covers is:

. The arc is 1/5 the entire arc/circumference of the circle.
Now find the circumference. Remember that the equation for circumference is

, where c=circumference and r=radius. You're given that the radius, r = 6.48 in. Plug that into the circumference equation to find the circumference of the circle:

Now multiply the fraction that the arc covers by the circumference. You know the arc is 1/5 the circumference:
The length of the arc PQ is about 8.1 in.
Answer:
A = 22, B = 28, C = 18
Step-by-step explanation:
So you just needed help w/ C, right? Measure the bottom rectangle first, 6 * 2 = 12. Then add the area of the triangle on top. The area of a triangle equals half of base times height. In this case, it's half of 6 times 2, or just six. 12 + 6 = 18.
False
<span>sin of an angle in a right triangle is equal to the ratio of the length of the opposite side divided by the length of the hypotenuse. </span>
