When I solved it the answer I got was m=9
Circumference = 2 x radius x Pi
Circumference = 2 x 15 x 3.14
Circumference = 30 x 3.14
Circumference = 94.2 feet
Answer: the value of x is 15°
Step-by-step explanation:
A is 2x. B is 2(2x), so 4x. C is 3(2x) so 6x.
The sum of all the angles of a triangle is 180°
Set up the equation:
2x + 4x + 6x = 180
12x = 180°
x = 15°
Answer:
R=50 degrees
Step-by-step explanation:
All of the angle measures together are 180 degrees. You need to make an equation in order to solve this problem:
180= (3x+5) + (11x-1) + (5x+5)
You then combine like terms:
180= (3x+11x+5x) + (5-1+5)
180= 19x+9
Then, subtract 9 from 180:
171= 19x
Then, divide 171 by 19:
9= x
Finally, you plug the value of x into the equation representing angle R:
5 x 9 + 5
45 + 5
50
