Answer:
√13
Step-by-step explanation:
Plug into Distance formula --> √(0-(-3))^2 + (0-2)^2
---> √13
Y-3=(-5/2)(x+4)
y-3+3=(-5/2)(x+4)+3
y=(-5/2)(x+4)+3
y=(-5/2)x-10+3
y=(-5/2)x-7
D
Answer:
A'B' = 8, M<A' = 37
If the scale factor is 2, then every coordinate point of the original triangle is multiplied by the scale factor 2.
88 degrees is the answer. You would start by setting up the equation as (5x+7)+(8x+8)+(3x+5)=180 because all angles of a triangle have a sum of 180 degrees. From there you combine like terms which would leave the answer of being 16x+20=180 then you subtract the 20 from 180 to get x by itself. Then that would leave you with 16x=160 then you divide both sides by 16 to get x=10. From there you plug 16 into the x in the planetarium equation which is 8(10)+8 which equals 88 degrees
