Answer:
x = - 1, y = 3 or (-1 , 3)
Step-by-step explanation:
x – 3y + 10 = 0 x = 3y - 10 ... plug in
x² + y² = 10
(3y-10)² + y² = 10
10y² - 60y +90 = 0
y² - 6y + 9 = 0
(y - 3)² = 0
y = 3
x = - 1
Vertical angles are equal, and parallel lines have the same slope.
The answer for this question would be
B) Identify property of multiplication or the second option because since the result 20 is the same as the 20 multiplied against 1. * I take no credit for the image below I just found it off google. ✅
I know 17. The formula for INTERIOR angles is 180(n-2) divided by n. therefore 180(6-2) / 6 = 180 x 4 / 6 = 720 / 6 = 120.
and EXTERIOR angles is 360 divided by n, therefore 360/6 = 60.
