3 x 5/7 + 2 x 6/7
15/7 + 12/7 = 27/7 or 3.85714286
C.(x,y)--->(-y,x)
i hope it's right!
We could find x by finding the leg of the implied triangle.
We could use Pythagorean’s theorem for this
a^2 + b^2 = c^2
Plug in values
(17)^2 + b^2 = (19)^2
289 + b^2 = 361
b = 6 square root 2
We multiply this by two because there are two of these
This makes it 12 square root 2
Subtract this from 31
This will be 31-12 sqrt 2 or 14.029437...
Answer:2
Step-by-step explanation:It’s like doing 6 minus 4. Then use the symbol from the largest number
1) "a" and 60° are vertical angles, hence equal. a = 60°
2) "b" is the supplement to 60°, so is 180° - 60° = 120°. b = 120°
3) "d" is the supplement to 65°, so is 180° - 65° = 115°. d = 115°
4) "e" and 65° are vertical angles, hence equal. e = 65°
5) "g" is the supplement to 55°, so is 180° - 55° = 125°. g = 125°
6) "h" and 55° are vertical angles, hence equal. h = 55°
