Answer:
C. x = 40
Step-by-step explanation:
1. Get the supplementary angle of ∠9: 180 - m∠9 = 180 - (4x-10)
2. The inside angles of that triangle add up to 180: 30 + 3x + 180 - (4x-10) = 180
3. Solve for x:
30 + 3x + 180 - (4x-10) = 180
30 + 3x + 180 - 4x + 10 = 180 Distribute negative to parenthesis
220 - x = 180 Combine like terms
-x = -40 Subtract 220 on both sides
x = 40 Divide both sides by -1
Answer:
40
Step-by-step explanation:
the length would be 40 because four tens equals 40.
Answer:
but dude what to answer............
Answer:
Step-by-step explanation:
A
Never terminates. The answer is 6.1111111 ....
B
3^3 and 27 cancel. 3^3 is 27
5^2 and 5^3 partially cancel, you are left with 5 in the denominator.
2 is raised to the 1
1/(2 * 5 ) = 1/10 = 0.1 which terminates right where it is.
A non terminating repeating expansion
B terminating decimal expansion
