Answer:
the answer in decimal form is 21.009
Answer:
x = 35°
∠Q = 127°
∠R = 35°
∠P = 18°
Step-by-step explanation:
x + 2x + 57 + x - 17 = 180 {Angle sum property of triangle}
x + 2x + x +57 -17 = 180 {Combine like terms}
4x + 40 = 180
4x = 180 - 40
4x = 140
x = 140/4
x = 35
∠Q = 2x + 57 = 2*35 + 57 = 70 +57 = 127°
∠R = x = 35°
∠P = x - 17 = 35 - 17 = 18°
Answer:
3√265
Step-by-step explanation:
The distance between the given points is √265. If all the side are the same length on an equilateral triangle, then the perimeter is 3 times as long.

Steps To Solve:
-27 + m = 3m + 9
~Subtract m to both sides
-27 + m - m = 3m + 9 - m
~Simplify
-27 = 2m + 9
~Subtract 9 to both sides
-27 - 9 = 2m + 9 - 9
~Simplify
-36 = 2m
~Divide 2 to both sides
-36/2 = 2m/2
~Simplify
-18 = m
------------------------------------------------
Answer:
m = -18

Hope This Helped! Good Luck!
18! is common to each term in the sum:
18! + 19! + 20! = 18! (1 + 19 + 19×20) = 18!×400
The largest prime factor of 18! is of course 17.
Meanwhile,
400 = 16×25 = 2⁴×5²
so the largest prime factor of 18! + 19! + 20! is 17.
