Answer:
Step-by-step explanation:
8x = 9x - 7
-x = -7
x = 7
9(7)-7= 63-7=56
8(7)= 56
13y+7+56=180
13y+63=180
13y=117
y=9
13(9)+7= 117+7= 124
5y-11+56=90
5y+45=90
5y=45
y=9
5(9)-11+9(7)-7= z
45-11+63-7=z
34+56=z
90=z

Answer:
8 units
Step-by-step explanation:
Note that 120 degrees represents 1/3 of 360 degrees. The arc described here is thus 1/3 of the circumference of this circle.
Find this circumference and then multiply that result by 1/3:
The formula for the circumference of a circle with radius r is C = 2πr. Here,
(1/3)*(2)(π)(4 units) = 8.38 units, or (to the nearest integer) approx. 8 units.
7/20 is equivalent to the decimal 0.35
