Answer:
9.4868329805051 or 9.5
Step-by-step explanation:
Answer: H' = (-4, 4)
<u>Step-by-step explanation:</u>
H = (-4, -4)
reflect across y = -2:
H is 2 units below y = -2 so when reflected it will be 2 units above y = -2
--> t<em>he x-coordinate doesn't change</em> the new y-coordinate is: 0
H' = (-4, 0)
reflect across y = 2:
H' is 2 units below y = 2 so when reflected it will be 2 units above y = 2
--> t<em>he x-coordinate doesn't change</em> the new y-coordinate is: 4
H'' = (-4, 4)
Answer:
36degrees
Step-by-step explanation:
2x + 26 = 3x + 21
2x - 3x = 21 - 26
-x = -5
x = 5
m<B = (3x+21)°
m<B = 3(5) + 21
m<B = 15+21
m<B = 36degrees
