Answer:
3i √3
Step-by-step explanation:
you can't have the square root of a negative number
so we use "i"
That equal 1 because they are the same
It might be the first one or the second one. i said MIGHT!!
<4= 150
<6=150
because the angels are parallel <4 & <2 are the exact same measurements and because 6 is perpendicular to <4 & <2 thus making it also 150 degrees
Y = 3x
so
if x = 5 then y = 15
if x = 10 then y = 30
so a = 10 and b = 15
answer is B. second choice
a = 10 and b = 15
