Answer:
arc length =11
Step-by-step explanation:
To find the arc length , we take pi *2 r and multiply by the fraction of the circle
The circumference is 12 which is equal to 2 * pi *r
arc length = 12 * 330/360
arc length = 12 * 11/12
arc length =11

Step-by-step explanation:
Answer: x = 28
method: You have to get the three missing sides of each shape, one of which you can get straight away because there's a rectangle in the middle and in a rectangle, opposite lines are equal, therefore, the missing length is 10. The other two lengths are the same because the dimensions of each triangle is the same, so you can just find one and multiply it by 2. To find one, you need to use Pythagoras' Theorem (c^2 - b^2 = a^2), so 15^2 - 12^2 = 81, and the square root of 81 is 9. 9 × 2 = 18, so added to the 10 you get your final answer as 28. I hope this helps! Let me know if you need me to explain it more :)
Answer:
The other two numbers depend on what type of triangle it is.
Step-by-step explanation:
if if it is isosceles and may vary however if it is scalene the measures of the other two angles can vary greatly and it will not likely be 45 degrees to 45 degrees.
Answer:
True!
Step-by-step explanation:
The palm has five bones known as metacarpal bones, one to each of the 5 digits. These metacarpals have a head, a shaft, and a base.
